Bright and tough flashlight
Outstanding light. I use a flashlight every day and this one has really worked out well. I've had it about a month. So far it's super bright, twists easily to go from flood to spot, price was very good, and has a nice knurled rubber grip. And I've dropped it a few times from about 5ft with no problems. Still working great. I would recommend this product.

I seem to have a thing for coast flashlights
So, this is my third coast flashlight and I didn't really "need" another one, but my original Coast flashlight is suffering from some issues where it seems to have a poor connection with the power supply. What I like about these flashlights is they still offer battery powered options, instead of a "rechargeable" variant. I like having the freedom of always being able to plug in fresh batteries and the flashlight works and not have to worry about a rechargeable battery degrading over time. In addition, the price is much better positioned for what you get and for this specific model I really like the textured/rubberized surface which really makes it great to hold. Rear button activation is my preferred method, so it has everything I want. It's plenty bright but could always be brighter! Unsure how long the batteries will last, but it did come with 4 already pre-installed and ready to go and then I'll be switching to my eneloop rechargeables when those die off.

Good light for emergency use
Good flashlight, bought it to go inside wifes new car. Plenty brite to check tires or motor at night, or what ever little emergency that might come up. Large enough she can find it easily in a dark car. But not bulky or heavy to be inconvenient for her

Very pleased with this flashlight
Bright, compact and just works! I also own two Coast G60R flashlights and they're great, but I think I like this better because sometimes it's good to have a flashlight that uses easy-to-purchase AAA batteries. You can buy a rechargeable battery pack for this model but it is expensive. If you want rechargeable get the G60R model which includes rechargeable batteries.

Reliable
It’s a good flashlight! It is bright but not as bright as I was expecting. I think if you buy the rechargeable battery specifically for this flashlight it will be extremely bright! The AAA batteries I used just didn’t seem to be enough for me. Still, I do recommend!

Less light than my Single Cell AA Coast
Overall like the light, but the amount of concentrated light the unit puts out with 4xAAA batteries is about the same as my smaller HP1 in my opinion @ ~100 yards, even though they have materially different lumen ratings. The HP1 was a great unit and still wish it was made by Coast. Dislike: Proprietary battery setup. Does not use a standard 3x or 4x AA setup and has a funky extended adapter to allow use of AAA batteries instead of the Lithium that is recommended. Like: Like other coast products is well made.

Great brightness
The flashlight has a great brightness and is very light. One of Coast previous flashlights had a magnetic feature which was great when storing it-wish this one had the same thing. Other than that I would definitely recommend.
