KeyUnity KF00 Titanium Mini Keychain LED Flashlight, 15 Lumens Waterproof Electric Torch Light Handheld Size Single Mode for Camping, Hiking, Climbing, Fishing, Backpacking (KF00 Sandblasted)

Light and bright, it suits me very well. I have relied on a pocket knife with a light for many years, but this is better because it's much brighter and I don't have to apply constant pressure with my thumb. I also switched to a knife / fingernail clipper combo and I am happy.

It is exactly what was described. Bright and easy to use. Would recommend.

I wrote a negative review on product, after I cooled down the fix was simple. I was going to return the product but I actually liked it too much. Nice little flashlight. Apology to seller

The KF03 build quality is great. Small size and light weight. Smooth turning action. Very bright for the size. I believe at this size this is the best keychain light on the market. I wish these were USB-C rechargeable and had two brightness settings but you won't find that on a light this small as of the writing of this review.I also have a KF00 which is the smaller, less-bright version of the KF03. The first KF00 I received was faulty and I could only get it to flash on about a quarter second at a time if I turned it just right but the replacement worked fine. Acceptable failure in my opinion since I've now purchased about 10 different products from this company and this was the only defect.

No more fumbling for door keys at night even on a dark porch.

Nice and handy pocket light.

Because of its size, it takes a little practice, but it works beautifully!

A solid made teeny little flashlight. Make a great stocking stuffer as it comes in a little zippered kit (looks like fake carbon fiber) with the flashlight, spare batteries, the wire lanyard and no instructions. (Flaw 1)Batteries are already installed and all you need to do is twist the flashlight's pieces to make it light up.This is Flaw 2: It takes two hands to turn it on and off. Not terribly convenient when trying to find your keys or the lock or such things as you find you suddenly need a light for.The light itself is not super bright but more than adequate for emergency use. The beam is modestly focused but there is a lot of side spill. It'll find your immediate path but don't expect to use it to guide a lost group in dangerous ground.Tiniest batteries I have ever seen, at east as small as what you find in a laser pointer, which this sort of resembles. Really nice a full replacement set comes with. Can't say how long these will last though.Flaw 3: The cable. Watch the video in the item listing to see how to undo it but do watch out. This cable is like spring wire and flings itself open hard when released.It's a barrel catch with a very fine thread and I am not used to such Putting it back together is a job as the spring is very springy and holding both ends together to fit the connector back in the barrel was an exercise I plan to skip again if possible. You really need three hands as it takes considerable force to hold the ends properly facing each other plus rotate the barrel.Finally, this is just not a value at the listed price as of my writing this. Even if the case is solid titanium, and I have mo way to tell, I don't see this having that much value when there's plenty of good lights for a quarter the cost.
