Those [coupons] Amazon uses are fairly new & can be glitchy.
What I think happened; there was that big coupon in place, then they put that kit on a Lightning Deal & mistakenly left that coupon still active on the page.
Honestly, thought to myself seeing it in checkout, no way possible!!

My order went through. They have to honor it.

Looks like they fixed it.

Got Gifts :laughing:
I've got a bargain now and then online over the decades myself. I wonder if someone else saw the error and ordered a dozen of them it would be tempting to buy them and resell them and make an easy $100 profit (or more).

I added the Ryobi hedge tool to my cordless tools. It's the combo one with short wand and grass shearer. It made quick work on a pair of holleys I've been hand pruning for a few years now. They were stumps that had small growth poking out of them and I figured they'd hide my trash can/recycle bin some day and pruned them in a way that eventualy turned a few stalks into 4 foot round bushes. Once they were ball shaped hand pruning was a two hour per bush ordeal. The Ryobi shearer made a 3-4 hour job into a 15 minute job with even better results. I used the grass shearer to clip a branch or two I'd missed with the wand.

Only dilema was what to do with all of those clippings. Eh, more first world problems. There's an area in my back yard under an eve where nothing grows due to lack of water. I spread the clippings along the area and will cover them with mulch later this summer.

Having a number of yard & cleanup projects staring at me, along with being in the Memorial spirit this weekend, picked up a Dewalt DCS367B.
Projects not really for a chainsaw or brushcutter (and not entirely wanting to do by hand saw) the recio saw will make my life far easier.

btw, this is a fantastic deal on carbide blades: https://www.amazon.com/dp/B00YCV91QW/?tag=cpf0b6-20

Glad you got the brushless version, good saw but is noisy and vibrates a lot if you go full power. Those blades are almost out of stock now. If I had prime I would pick up a set of them as I rarely use wood blades. I tried my dewalt band saw on wood it is a bit slower but a lot quieter and smoother cutting but it won't fit in the places a recip saw will. I bought it for cutting metal mainly as I've had to use a recip saw to cut small metal objects and even bolted down it you can struggle with the backlash from the blade if you can't get a handle on the item. I have 9 inch wood cuttings blades one is a pruning blade the other a 6TPI blade and they cut differently for sure. I haven't used them enough to get a good idea of comparison yet only cut off one small limp with the 6 TPI blade and some other smaller limbs with the pruning blade. With my old Porter Cable recip saw it would struggle and tire, the the 367 dewalt is a monster even with a 3A 21700 battery it rocks.

An afterthought, I am using metal cutting blades in my band saw (fine tooth) so I guess it isn't surprising it cuts slower. I don't think they make coarse cutting blades for it like they do with wood and the blades are very thin compared to recip blades. Still it was cool to slice wood almost like cheese with it.

Thanks much for the tip. :thumbsup: I pulled the trigger yesterday.

Likely so or they played the "oops" we ran out apology game and canceled orders or something of that sort..

Well, UPS delivered that brushless kit today & it was factory sealed/brand new,, so a very rare [page glitch] was honored for $32.
the kit is now $119

________________________________________________________^

the reason I justified my DeWalt recip saw, was because of that deal

Regardless of the "deal" a brushless cordless recip saw is one of those tools you can really use especially if you live in a house and have to care for a yard. I've used a circular cordless saw on trees they are good for some things but nowhere near as versatile as a recip saw is. The advantage of a circ saw is the blade spins one direction instead of 2 directions the recip saw does which on smaller limbs you have to hold onto the limb with a good grip else it will shake it out of your hand.

Went to home depot today to pick up some pipe for Mrs Fixer and was contemplating a Ryobi 18 volt table fan. I was looking for the kit but all they had were "tool only". Mrs Fixer found a display where you buy a "starter set" battery pack for $99 and get a select tool at no charge. The fan was one of the tools. The starter set is a pair of 4AH batteries and a charger. Not the HP battery mind you. But still I had 2 batteries for my new fan. I ran it on low for 4 hours and still had 3 of 4 bars. The fan also has a facility to run it off A/C power too.

I've been eyeing the Dewalt 20V fan myself but not in the budget. A fan and 8Ah of batteries sounds like a steal to me. I would rather have 2 4A batteries sometimes than 1 8A battery as you can charge one while using the fan on batteries if it is too far away for the cord to reach.

A couple of years ago, those batteries were $100 each. On special sale days, like Memorial Day or Thanksgiving one could get two for the price of one. Now I see they are giving two for one plus a tool! Very cool.

I have one of those fans. I don't know if they upgraded it, but the head of the fan would not stay at the angle that I set it at. Eventually it would drop. Scout24, told me it put an "O" ring behind where the screw is that you would tighten. That worked well.

I looked for that thread, I think we had pictures, but I couldn't find it.

What I think is interesting is the odd or rare cordless tools you see on some lines some of which are becoming more common. I saw a 20v mister/fogger the other day by Hart and they have some others interesting tools like an inverter. I've seen a cordless sprayer too. What is sad is in order to have these uncommon tools you can end up investing in several tool lines partially.

One thing that does concern me that could happen in the future is if they start mandating electric vehicles replace gas powered ones in places enough we could see a tightening up of the lithium market and with that the prices of tool batteries could spike. I've read a few articles saying that in 10 years (or less) they could use up all the lithium being mined to make only vehicle batteries. I was also looking at Zinc-Ion battery technology which is interesting but the information about it is spotty online and I don't have the patience to sift through it all but it looks to be up and coming for large energy storage when it doesn't need to be portable like for power stations. It may possibly be a way to replace lead acid batteries in a lot of applications but until giga factories come online and the price drops below that of lithium ion tech it won't be making inroads. I think it likely won't be in tool batteries as the weight/power density is not that of lithium ion but it has one huge advantage..... it is a lot safer. It could be in lower power battery portable devices where safety is a concern.

I remember you being told about the o'ring Poppy. This one is pretty stiff and for the few hours I've used it so far stays in place well. If it starts slipping I know how to fix it. :naughty:

The "starter" kit has non HP batteries, which are fine for tools that don't have a high draw like my fan on low or 'dremel' style tool I bought Mrs Fixer. The tools like the brushless leaf blower or lawn edger are said to perform better with HP batteries.

Perhaps someday somebody will focus on hydrogen powered transportation and save all the lithium for computers, flashlights and power tools but I fear hydrogen tech will go the way of the Beta Max.

I like that invertor orbital. Maybe if I'm good Mrs Fixer will hook me up with one for fathers day.

The problem with fuel cells is that at their core they're very complex - and typically inefficient - batteries. Suspect that reality is why they haven't seen much success in the market.

I recall one HFC ecosystem was were targeted at video production that offered a commanding advantage in terms of runtime (I recall claims of being able to operate high-end digital cameras ala Red all day nonstop) however it was eye-wateringly expensive, pricing it well out of even the 'prosumer' tier.

Another concept I heard about were direct methanol fuel cells (DMFC) targeted at laptop computers but they also seemingly failed to condense from a vapor state - perhaps it was the proprietary blend of methanol the OEM would have forced upon the user base.

I thought that one of those inverters would be cool, but then I did the math and was very disappointed.

A 4Ah battery will only power the inverter for about 30 minutes, or less. It will only output 1.2 amps AC. I guess it might power my internet router, and charge my notebook, but not power my TV. I wondered... what would I use it for? Fortunately the batteries are quickly changeable, but there is a limited supply of them.

I used mine during a power outage a few months ago to power my laptop and the cellphone it was tethering to. Ran for about an hour, consuming a single bar of the 9Ah battery I've got. I've also used it on occasion sheltering in my house's de facto storm shelter (read: the fully interior 'powder room' half bath) to run phones on USB power and provide a low-level light - not because it was absolutely necessary but because I found the relative darkness more comforting when the tiny ~35ft² room was occupied by 2 humans and ... too many ... pets.

Last evening the Mrs and I continued working on a chest of drawers but this time it was after dark under a 15x15 canopy. A typical June day is hot in my state but there is usually a breeze blowing as hots and cools collide all day long. Working under a tarp provides shade. After dark not so much. Enter the Ryobi fan. It kept our outdoor work space much more comfy by providing that gentle breeze of the daytime. For better battery life I had it on low. Then it dawned on me that a wall outlet was 8 feet away and the fan runs on AC current. A minute or so later it was running off the all night generator a few miles north of me……on high.

For light we used a pair of COB lights magnetized to metal poles in the ceiling of the tarp. The ceiling is a light gray nylon that acts like a photographer's reflector so aiming one up into the ceiling provides a well dispersed lighting that reduces shadows.

I thought "man, what a great time we live in".

All that ceiling bounce really helped.

After applying a third coat of stain we changed our mind.
We learned the hard way why one should use a pre-stain product to wood prior to applying oil based stain. Lots of really dark, nearly black places popped up. Although Phillipine Mahogany is listed as a hard wood it soaks up oil based stain like a soft wood. So after dark we gave up trying to polish the excess stain by hand and reapplied finish remover. Next we'll sand it back down to bear wood and apply a wood conditoner.

Edit:
I tried a non HP battery on my leaf blower said to put out "up to" 100mph (280 cfm?) and it ran fine in a normal mode, which I'd surmize as maybe 60mph with the "up to" being a sort of turbo mode. Well it would not engage the turbo like an HP battery but other than that it ran like normal and did what I wanted it to do. Normally I use turbo to kick loose stubborn stuff when using it as an electric broom. Today I just used the scraper at the end of the outlet that I did not was even there until today.
End edit.

Inverters take a lot of current to operate which takes large capacity high current batteries. To get 1.2A AC from an 18v (20v under load) battery it takes about 6 times the current or 7.2A plus the losses in conversion so could be close to 10A of drain on the battery which would equate to about 25 minutes off a 4A battery. They make 1000 watt inverters for cars (about 8A @ 120v) these take 10 times the current plus losses from a 12v car battery so we are looking at likely more than 100A from it. This is the reason people buy generators as a gallon of gas beats a stack of tool batteries hands down.
