Bests & Worsts Reviews from Amazon

After having these for a few weeks, I have decided NEVER to order this brand again. My fist purchase one of the lights had a motion sensor that didn't work. Amazon was great and refunded my money, and I ordered another set. When I received the replacement set yesterday, I charged up two of the lights for the recommended time, and again, one of the lights had a motion sensor that didn't work.The light stays on continuously all the time in both the "on" AND the "automatic motion sensing" position. Amazon was great, but the product is lacking in consistency of quality. The other two lights work as they should. HOWEVER, out of all six lights now only three work as they should in the auto-on/off motion sensing switch position. I expected more reliability for the price of this item. $31 is a lot, compared to other lights of the same functions. I paid more, expecting to get a better product where all three worked. While I am disappointed that all three don't work correctly, the two that DO work throw off a nice amount of light on my stairs and the recharging ability is nice so I don't have to keep replacing batteries.
