Review on Enhance Safety with Cadrim Puck Lights Motion Sensor - 3 Pack, Rechargeable & Wireless LED Stick on Lights for Stairway, Hallway, Bathroom, Closets by Monica Moore

I've had them for 3 months now and I think they're fine. There are a few things I don't really like: 1. The magnet inside the puck isn't strong enough to stick to the metal plate that comes with it. The washer sometimes falls off or sags. Do not install them high or they will break if dropped.2. The switch gets stuck. Now you have Puck Light with ZERO.3 modes. The IR sensor is very erratic, when climbing stairs, my foot immediately turns on the light. On the descent it takes 1-2 seconds for the light to come on, I'm standing next to the puck and nothing. The good thing about this product is that it is rechargeable and the light is bright. These lights will last 3 weeks before needing a charge, this of course depends on your footfall.
