These things are awesome. I already lost one but that is of no fault to the manufacturer! They are small though.. but they produce a lot of light for their size.

So far, I like these lights a lot.  I'd like to say I love them, but it's too early yet to tell.  I have placed them in the basement where there is a room with no electrical outlets and therefore no lighting.  I like their small size - they fit nicely into a tight area and it will take quite a tug to get them unstuck so be sure of where you want to adhere them.  The sticky tape is very secure.  The "push on" feature is very easy to use and each LED light produces a very bright light.  Combine all three and the previously dark area is lit up and easy to see what's what.  Each light takes 3 AAA batteries which, unfortunately, are not included.  However, they are easy to insert but I hope they don't get drained very quickly by the LED lights while not in use.  So far, I think these lights deserve fully 4 stars and possibly 5.

As most other reviewers have said this light is amazing for it's brightness on one single AA battery.  It is also very well made, of metal and not plastic.  I think it is a great bargain for a small light, that will work well in small or tight places.

My only reason for not 5 stars is that if it has some settings for brightness, as suggested by some reviewers, then some instructions would be helpful.  No instructions came with it.  Delivery was much faster than projected, since it comes from China.

I was surprise! I thought for a camping lantern it would bigger, but the lantern is just 4 inch. But great thing comes in little package. So the size doesnt really matter with this little LED lantern. It is tiny, but don't be fool by its size. The small size probably is one of its advantage because you can just throw it into your backpack. It is bright for its little size. The battery life last about 4-5 hours on brightest setting. I have not test the waterproof feature, but I think it will do fine.

Great Light in a small package. However 1 of the small magnets was loose out of the box.

I ordered a couple of these little guys, and have been impressed. The ones I got were the newest 45-lumen version. The pocket clip is great, and positions the light nicely in a pocket. The light itself is a lot brighter than you'd expect from such a small package, and the battery life is excellent.

Compact/Small/Bright.  I love that the lantern is small, especially for the amount of light it produces.  It lights up an entire room.  I love the hook and handle on each end.  I ordered two and have just ordered two more.  We have a lot of power outages especially in the winter so this is really going to come in handy.  It would be helpful to have more visible indicators on the battery compartment to know which way the batteries go but I'm not going to drop the rating because of that.  There are indicators there but being black plastic it is a little difficult to see.

These lights are tiny but have amazing light output.  Each one has two super-bright, surface-mounted LEDs.  I wish I had the equipment to measure the actual lumen output, but I'd guess its around 30 - 40 lumens.

I built a (very bright) night light out of one of these lights by putting it in a frosted plastic enclosure.  The frosting diffuses the light 360 degrees and lights the room quite well without ruining your dark-adapted vision.  In this application, I used a non-working iPhone sync cable - I cut the "lightning end" off and soldered the bare wires to the light.  The other end of the wire, of course, is the standard USB plug that fits any USB port on a PC, laptop, AC wall charger, portable battery pack, etc.

If you're not building a very bright night-light, one of the nice features of these lights is that you can insert them into the USB port facing either way, so you can shine the light in the direction you want.

The description says the hole near the rounded end is for use on a key ring.  I'm not sure how well the bare, surface-mount components would fare on a key ring in your pocket and haven't tried.  On the other hand, at a unit price of about $1.30 each, you wouldn't be losing a lot of money if a light were damaged while on a key ring.

The dimensions listed in the product specs are for the packaging.  Each light is very small - approximately 26.5mm x 11mm (1 1/16" x 7/16").  Also, the product specs list each light as 1 watt, but my USB multi-meter shows less than 0.5 watts (0.46W) actual power consumption.

All said, I like these and bought several packages of them.  I'm not sure exactly what I'm going to use all these lights for, but I'm kicking around some ideas in the back of my mind...

Packaged well.  Clear installation instructions.  Very bright-be aware that these are individual small LED lights in a row-order frosted cover if you want more muted light.

Good little lights. They are bright, and easy to install.

Great deal for a pair of mini flashlights.  Very small and lightweight so very easy to throw in your purse to have just in case or around the house if the power goes out.  Fits in the palm of my hand.  Takes just one double AA battery.  Very bright and you can adjust to turn it even brighter.  Pictures I've taken below are in pitch black so you see how bright they are.

I purchased this Headlamp from Moma Group Limited. I was impressed with the small size and the power of the LED.  Nice small package. I recommend this product for multiple uses.
