I took a shot on this little guy to add to my flashlight collection. Not bad at all. Construction is great and feels very durable. The button has nice tactile clickyness and should last a long time. The only drawback is using AA batteries as it's not very bright, I suspect 14500's would be ideal. The zoom is smooth and useful. No QC issues with this one and a true bargain. Now I need to buy some 14500 lithium ion cells :P
