Have the Nitecore D10 issues been resolved?

Hi,

I bought Nitecore D10 s/n 00712 when they first came out. I loved the small size and simple interface. But, the switch has never been reliable and requires a lot of force to press the button.

I did the normal things to make it better like using silicone lubricant, different orings, used contact cleaner, etc. This did help some for a while. When I replace the battery most times the switch does not work correctly and I have to open up the flashlight and piddle with it.

Are the new (currently shipping) Nitecore D10's better?

I had same problem with you when i got it at first day, i've tried using silicone lubricant even i used vaseline to lubricate the piston. It's just work for 1 - 2 and the piston become stiff again for few days.

Untili tried using deoxit and deoxit gold. First i clean the piston using deoxit then after cleaning process i use deoxit gold to lubricate the piston. With this lubricant, personally i feel the piston pressure is much smoother and better.
 
Tell me what other light do you need to do all these voodoo tricks and magic to in order to get working?

These are $60 flashlights. If you bought a car, a nice one at that, and you had to fiddle with the ignition, oil the o-rings, change the type of battery you are using, etc just to get it to operate, would this be acceptable to you? I think CPF is the nicest bunch of customers out there, of any hobby or market.

Keep in mind that for every person you hear complain that the switch isn't want they expected, there are probably dozens more who are perfectly happy with operation right out of the box.

Also keep in mind that ALL lights, regardless of brand, should receive proper maintenance right out of the box. They often don't because of lazy owners, but they should.
 
Sorry Marduke, that argument doesn't hold true here. You make it sound like a LED that doesn't turn off or lights that don't activate or function properly is the fault of the customer.

What people expected is a light that works as claimed. I guess JHanko's expections were off since he "expected" a light to turn off.

Maintenance on lights is a simple clean and lube. And you should be golden for months or years. Out of the box, I don't expect to have to maintain or FIX any light and in fact never *had* to get them working, except for Nitecores. I do anyway as a preventive measure but it was as simple as putting on some lube. Not having to take out jeweler's screwdrivers to fiddle with a component, or rotating to (as one user put it) find the sweet spot. The sweet spot, so my light can turn on? You have got to be kidding me.

That's your idea of proper maitenance? Maintain means to keep in (the same) condition. It doesn't mean to fix defective products out of the box.
 
FWIW, I have one of the first pre-ordered D10's and have never had a problem with it at all. I've probably lubed the piston twice in well over a year and it is my most carried light ever.

I'll chime in too because I've purchased nearly a dozen D10's and EX10's and had ZERO problems with any of them personally. By default I always disassemble, clean inspect and re-lube ALL of my newly purchased lights. I use Krytox or Nyogel exclusively. Nitecore uses/used a grease that was a little thick and created stiction. It's well documented here and takes all of 1 minute to wipe off the piston. Big whoop. I've given many D10's as gifts and I'll tell you what I think is the "problem" with the glitchyness of these Piston Drive Nitecores. WEAK HANDS. That's right! Women, children and girly men don't have enough muscle to consistently work the light. I've modified several of the ones given as gifts to lower the amount of force required to operate it and the problems went away immediately. A word of caution though, the lighter pressure increases the risk of inadvertently turning the light on if carried in your pocket. There's always compromises and you can't make everyone happy!

You need to separate my two different statements.

1) There are relatively few "issues" that require warranty work vs how many units are sold.

2) Most of the "complaints" involved people who complain not about how the light works, but how it feels. They don't clean and lube the light to start with (something you should ALWAYS do with EVERY light), or complain about it being hard to press, etc. The light doesn't feel like a regular clicky switch, which throws them off and they ***** about it.

Those are my observations after following the PD threads closely since the very first ones over a year ago.
 
I've been an EX10 guy but have recently started using a D10 magma special edition I purchased a while back. It was used when I got it but it looks like new and has worked flawlessly. I did purchase a new D10 R2 recently and had nothing but trouble, sent it back immediately, I'll wait awhile before I'll get another.:grin2:
