## Customer Reviews

### ⭐⭐⭐⭐⭐ Small, light-weight
*by J***S on May 24, 2022*

Nifty little light, has everything you may (or may not) need in the box, including a couple of batteries and a zip tie (and some spare O-rings and whatnots). Battery lasts surprisingly long: I've done 3 30-minute dives now on the same battery, it's still going fine, especially surprising since you turn on this light before you go submerge and you turn it off after you're out (I've forgotten to turn mine off for 20 minutes out).One note: this is a small light-weight light, it is not a half-mile torch. It is for near-use mostly, such as to indicate your position/signal to your buddy or to examine a crab. Do not expect it to light up the night.I got two and I'm definitely using both.

### ⭐⭐⭐⭐⭐ Cool bright light with lots of settings.
*by C***E on September 5, 2023*

This thong is pretty cool. It has multiple settings, is very bright, and I don't know anything about scuba diving but it seems to blink every minute.It seems to be good quality and though we haven't used it in the water yet, we do use it daily to look at our rock collection and such.

### ⭐ I had failures on 2 of these lights
*by T***G on September 7, 2023*

I purchased a model DF40 in 2022. I could not get the light to turn on. It seemed that the O-ring would slip out of its groove, fall down upon the electrical contacts in the head, and prevent the light from coming on. I received a replacement light promptly upon return of the first light.The second light had the same issue where the O-ring would not easily stay in place. After many tries, I did get the light to come on, and then took it diving in the Bahamas, but not until July of 2023. I am sad to say the light flooded on the first dive, and now will not on. The light is compact, and stored easily in my BCD pocket. I had a retractable lanyard attached to it from my BCD. Above ground, the light was very bright, and very white, which would make it great for underwater exposure of the true colors of hard and soft coral, as well as any fish or creatures hiding in crevices.As I didn't use the light until well beyond the 30-days from purchase date I cannot return it for a refund.
