Perfect! It's brighter than I expected. The push button is higher quality than I expected as well.They're VERY affordable, light weight, with strong adhesive and they're small enough that they don't look bad.Highly satisfied.

Excellent small and bright led light that is great for small areas and at an excellent price.

Easy to attach under cabinets with soft light for illumination. A little smaller than I anticipated, but they work very well

Finally reviewing these puck lights.The brightness is excellent. I haven’t had any duds , as of now, in any of my packages.I use them in random places. Sometimes used as a night light, when a regular night light isn’t enough, but a room light is too much. Stuck one on my drill when I needed more light to work. Stuck one on magnification glasses while I was working on a small solder.I’ve left two or three on over 12 hours, and they still “work”- Definitely not enough by that point to illuminate a small space, but I could find a pen or something in the bottom of a small bag.I would estimate , that if the end user received a good pack, the stated longevity of 10 hours is accurate- with reduced luminance.The biggest draw to purchase this product was replaceable battery.Rechargeable lights are fine, cost effective options-when you have electrical accessibility or a method to recharge. Replaceable battery is good as a backup if you don’t and have access to the batteries you need. I try to keep both options on hand and ready to use.The BEST way I’ve found to open the compartment to change the CR2032 battery is using needle nose jewelry/ small pliers( straight or bent nose). A little extra strength is possibly needed to initially break a seal, but done once makes repeated battery changes easier.The package says the item is “waterproof “. I haven’t tried these in a situation where they were submerged in water. I would guess they are waterproof when new (battery not replaced) and if the compartment is later opened to replace the original batteries, the effect is reduced. I may test water resistance after adding an o-ring between the main housing and components.Takeaway:Great for minor lighting needs in the home, stored in vehicle, taken on trips, lighting models/ dollhouses, working light or illuminating a small space where light would be beneficial.The estimated usage/run time seems accurate (if original batteries not degraded in storage).
