Just goes to show that these lights are inconsistent. I have owned several of both of these models with failures within the first year, and with very light use.
Many have commented that we tend to get what we pay for, as if these are cheap lights. They may be, compared to Zebralights and others, but when I consider that I have owned even cheaper lights from Walmart that have lasted far longer than these, it makes me wonder what's going on.
Cheap is a relative term. A $3 flashlight purchased in 1980, plastic, incandescent, disposable, is equivalent to that $10 LED today. Also consider complexity - that $10 LED of which you complain had an electromechanical mode switch which any engineer would tell you is the most likely point of failure. Obviously you weren't the only customer to see such a failure and the company updated its design to eliminate mode switching, sacrificing features for long-term reliability.
With regard to inconsistency, these are small electronic or electromechanical devices with manufacturing cost of a couple bucks. There simply won't be much QC at that price point. They likely test one in twenty or one in fifty to see that they'll light up when given power (head onto fixed power jig only).
Keep in mind that a $10 item purchased from Amazon, if it fails, won't even be returned. Amazon will simply take your word that it doesn't work and refund the $10. The amount of time I've spent posting two replies in this thread, if done at work, would significantly exceed the $10 price of your year old failed light.
I'm assuming you are, like me, no spring chicken. It amazes me when I pause to reflect on owning multiple *flashlights* that cost well north of a C-note. It is, frankly, insane. But that C-note ain't what it used to be. Filling my gas tank and buying a few cups of coffee at Starbucks will leave me a few coins in my pocket. The only redemption is that a $150 flashlight can be sold in the forum here for $100+ a couple years later so it's not just consumed like fuel and coffee. (... and let's not even get into $2.50 CR123 batteries my lights can chew through in an hour ...)
