The HC 75 is an Absolute Power House! You can have low light or Bright Enough to land a Small helicopter! It’s Truly worth every Penny!

Purchased this for walking my dogs at night or early morning before sunrise. I wear the NU53 while walking with them and when cars drive past, unless I'm looking in their direction, they may not see me or the dogs.

That being said, the lights attach to their collars easy. Slip on and anchor to the inner portion by the adjustment holes. They're positioned on the side, so when they turn and walk it's visible.

The bright white flashing works best in night and dark conditions. The blinking red works best with dusk and fog.

Overall, happy I found a small, light weight product that works as designed.

Great product. Glad to have the extra battery for light

Sweet item. Super bright, easy to carry.

Great light, durable and bright, battery will last a few days before recharging mind you I’m a mechanic and it sees daily use, although is small enough to fit in your pocket I found that it will fit perfectly in the belt pouch for the maglite mini, looking to get a 2nd battery for back up

I love the light

Really nice light for my hard hat in evenings . Super duper bright .. battery last a good bit too .

product was as advertised and delivered on time

Best keychain flash light ever

out of box works good time will tell

I typically carry a spare 18650 battery when I’m out for a full day in cold conditions, expecting to swap it out halfway through. On a recent trip to Japan, I only needed one—the charge lasted the entire day and even covered two shorter outings without needing a recharge.

Performance in low temperatures was noticeably better than standard 18650 cells I’ve used in the past. Output felt strong and consistent throughout the day, with no sudden drop-offs that sometimes happen in the cold.

Overall, these batteries delivered exactly as promised and performed reliably in freezing conditions.

It’s a great light. While it is compact in size it is not compact in performance. It’s well made and simple to use.

This compact charger really does pack a wallop! I love the rbg lights, no practical purpose but cool just the same! It feels like it is a quality product so we will see how it holds up over time. So far, so good!

Good

Great, light weight, charged my phone twice, flashlights.
