I'm hoping this is representative of most other units. - Streamlight TLR-8 G Sub LED 500 Lumens Weapon Light w/ Green Laser

I am giving this particular unit 5 stars, but I also feel compelled to disclose that my experience with this product line has not always been stellar.

Mosst of the problems i have seen have been with the laser adjustment, either screws that were too tight to move, too loose to hold, or if you went beyond an adjustment range, you could never get it back.

But, this unit seems just dandy, and in the past, I have verified that Streamlight does in fact have excellent warranty service, so if you check out the QC yourself, you'll definitely get a reliable. I think I have 7 of these now, and overall I think that even if they still do have a high assembly defect rate, the end result of a working unit that I haven't seen fail yet, mechanically or electronically, make them an excellent product.

It's very possible that Streamlight has cleaned up their assembly process for reliable laser adjustment so as to make out of the box reliability concerns a non-issue. I hope so. I would definitely recommend giving it a shot. The quality of light, laser performance, durability, and reliability of the electronics seem pretty excellent otherwise. These products seem to be in a nice sweet spot.
