Very useful if you don't want to explode!
Style: 90 Lumens
Found the unit a bit difficult to adjust on the hard hat but got it dial in eventually. Also impacted by the need to mount goggles on the helmet, that might be rare, but this was my situation working around chemicals.
nice and bright. batteries last a couple of days with intermittent use approx. 3.5hrs a day.
A bit of a pain to unscrew the cover on batteries but that's the nature of the beast to make sure no sparks escape.
Would highly recommend the product. Most other comparable products are around double the price.
BTW, the packaging looked like the driver dropped it on the road and ran over it a couple times...but it still worked.
UPDATE #1: After a few months of usage, the height adjustment is starting to fail. As I walk, the light begins to droop until it's shining down in front of me. Dissappointed that the adjustment didn't last longer. I might be able to discover a way to lock it back in, but have not taken the time to examine the mechanism yet.
UPDATE #2 9-2018: The adjustment problem has now reach its ultimate end. The hinge on bottom has basically disintegrated. Now, when I put batteries in and tighten the screw, the bottom hinge pops loose. The product is no longer usable. The hinge is just cheap plastic, that is a shame, I kind of expected better from nightstick. However, it still seems to be the best option vs. price available so I am planning to order it again. Hope I can get 3 years of intermittent use out of the next one. I do really like it when it is working...lite and bright.

Fantastic. They vary in thickness to accommodate different size punctures, they look nice, good value for the money, the sand out the tire and internal belt to stop leakage. and they easy enough the use.

These tire repair reamers work great for plug/other type repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These tire repair reamers work great for plug/other type repairs. Gone are the days of manually fighting a hand reamer through rough rubber. This is an efficient, neat and clean way to prepare a tire for the repair. Will purchase again as needed.
