Lenoxx FD1500

I purchased this Lennox FD1400 drone as a christmas gift for my kids and it will not power on. The battery is fully charged but the power switch seems defective.

We tried it on Christmas day and would only fly for a couple of minutes. We then contacted Lenoxx who sent a replacement controller. We can't even get it to fly. We shall contact Lenoxx for a refund. Not Happy at all
