Performance Tool ATAK Model 550 Pro-Focus 320 lumens Black LED Lithium-Ion Rechargeable Flashlight

25Jun2020: Switch holding up just fine. I never use internal charger as I found it to be problematic. I have an external charger and extra batteries. Still 5 stars.Works well. Has a range of beam concentration. Only two intensities w/out annoying flashing mode. Wide array of battery power (comes with 1800 mAhr and I'm using 9900 mAhr). As long as the switch holds out it'll be great. If the switch can be replaced it may last forever...

Only owned for a few weeks. It is well made. I especially like the location of the USB charging port.

it works some times

Reviewing the 320-lumen model:This is one well-made flashlight. Very bright. Zoom from flood to spot is simple to operate: just slide the lens in or out. The slide is well done; tight and smooth, not wobbly. The slide hides the USB charging port <--- a very nice feature, as it means no rubber stoppers to fumble or lose. Overall, it's a good balance, size-wise: not so small as to be easily lost, not too large to hold with one hand or hands-free in your mouth, and just tidy enough to fit in a pocket. The metal pocket clip is convenient but not obtrusive. The switch on the 320-lumen model is a rubber-covered pushbutton in the end of the cylinder; you can find it one-handed without having to feel around for it.BEST FEATURE OF ALL, THOUGH: Simple on-off; no light levels to negotiate, no obnoxious strobe. It turns on and off when you tell it to, with a single button-press. This may seem like a minor feature, but stop and think about it: how many times do you want to have to push the button EVERY TIME you turn it on or off? And what idiot thought is was a good idea to build a strobe effect into a flashlight and implement it so that it flashes you EVERY TIME you go to turn the light off? This simple on-off feature is getting harder and harder to find. This flashlight is solid and has lasted through a year of daily use, and when it wears out, I will keep buying new ones for as long as they make them.I read one reviewer complain about it not working well as a baton. I think this user must be either mistakenly writing about a different flashlight, or has been paid by another vendor to give a bad review. This flashlight is not sized or shaped to serve as a baton. If you want a baton, then get a baton. This is the best medium-priced flashlight on Amazon, and better than many of the more expensive ones.One final note: After buying the first one and being tremendously satisfied with it, I decided it would be wise to buy another one, lest it become unavailable, or superseded by a model with different features. To my dismay, it was not findable in any search on Amazon. I tried for hours, with various search strings and "users also boughts". Nada. Amazon thrust every other kind of flashlight in my face (and everything that even remotely had any variation of "Atak" or "attack" in its name or description), but not the one item I was actually, in precise terms, looking for. So, I left Amazon and tried a plain Google image search on the flashlight's one identifiable, searchable feature, the simple four-letter brand name, its only identifying mark, thinking that maybe it was available through some other vendor. And found it in a Google image search. Which then led me back to Amazon. It IS available on Amazon, hence this review, though you likely won't be able to find it in any Amazon search. Which is a shame.
