I live in an apartment in an old house. Closet lights did not exist when it was built. When I moved in I purchased some "pop" lights, as I call them, but quite often I was leaving them on. I have gone through a lot of batteries. It was time for a different solution!I first only purchased one just to see if it was too good to be true. It is amazing ! So easy to install and one lights up the closet better than 2 of the other lights which led me to purchase more. Because of my knack of forgetting to turn the light off I leave them on motion sensing which works like a charm.I am very happy with this purchase and would highly recommend them.Before I removed the tape to stick the magnet to the surface, I experimented in different places to get the detection to work when I wanted and not work when I didn't. Well, by doing so it ended up dropping 6 feet to the tile floor about 10 times. No sign of damage and it works like new. I would have like the auto shut off time to be longer, or adjustable, but it does what it says it should,Not very bright but helpful in a small space like a closet or laundry area. I will probably buy more in the future.This little bright light is a pure delight! It is sensitive to your presence and comes on and goes off when you leave the area. So thankful I bought a second one. Money well spent.I bought this as a gift at work to my team for placing underneath a piece of equipment that goes over a patient and produces shadows. This puts the light exactly where it needs it just the way we want it and since it's rechargeable it is exactly what we need and want. I love this thing and my coworkers do, too. Patients of complimented us on it, as well.the glue is not strong enough to hold the magnet after use of only a few weeks. as a result, light just keeps following down. remedy: buys gorilla glue to reenforce.I bought this to use it for me to go down the stairs at night. The motion sensor takes a while to register and the lighting is good but not super bright. I would suggest getting a stronger magnet too, I installed mine and it kept falling....LIGHT IS GREAT BUT AHESIVE IS NOT, KEEP FALLINGNeed recharging too often.So far work wellBien contente de mon achat le probleme cest que je suis toujours entrain de la recharger...une soirée et cest fini je doit la recharger , c'est sure que je la laisse allumer , je ne met pas le detecteur de mouvement , surment quelle ferai plus longtemps avec detecteur mais moi je laime allumé en permanenceBought this light for over the kitchen sink. Light only works when plugged in, and the charge cord is only 11" long. Tried charging it again, overnight. Still nothing. Don't waste your money on this useless piece of plasticI bought two of these for under my kitchen cupboards. One works perfectly but the switch on the other is loose but works if I tap it
