Burns finger tips and it electric shocks when plugged in

My finger got red and burned after use it for curing nails for about 30 seconds

I haven't even reacted yet, my finger was shocked and it hurts very much

Burns my finger nails

Make sure to use low heat setting for gel polishes though, or it might burn your fingers!

Every time I place my hand under it & apply a top UV Gel coat it starts to burn my finger after leaving it under for more than 10 seconds & makes a blinking light

Easy n fast
