Review on TSINGREE Rechargeable Temperatures Adjustment Brightness by Doug Mancilla

Initially it only worked when connected to a charger and I gave it a one star rating. The seller actually emailed me to fix the problem. Didn't want to worry about the logistics of returning (we are on Evacuation Level 1 due to wildfires and have to drive 50 miles to the drop off point). I also used a reading light with a power supply unit. In any case, they sent a replacement. I changed my rating to 3 because of their actions. The replacement has arrived and works as advertised. I use it when maneuvering on the street when I need my hands free. (It was a hot evening so a lot of work.) I'm impressed that they care about their reputation and their customers. I am now happy and impressed with their product. So five stars!
