I love these lights. They are bright and sense motion at a great distance. Rechargable with usb and last quite a while on a charge. Conviently attaches with adhesive magnet so you can pop it off for convienent portable lighting. Good for bed side and emergencies. I wish it had the option for constant on but auto off after about 15 - 20 seconds after motion activated. I'm extremely pleased with these lights. They work perfectly as described. I would be comgortable recomending this product.
