Query: Great buy!

These lights are amazing! I love the ambience but don't like the open flame option or the constant change of batteries and safe disposal of said batteries. Finally found a USB charging candle. They hold a long charge - easily up to 18 hours - and charge FAST. They are bright and flickering. I love the magnetic option but honestly haven't used it yet. Definitely worth the purchase. I would buy more if they had a bigger size option.
