Do not buy a Peticure. I kept mine plugged in because the battery is a piece of crap and it nearly set my house on fire. The cheap electrical plug was hot to the touch when I picked it up and I noticed that the carpet was singed!! I could not believe how cheaply made this product was but most importantly it is DANGEROUS. I'm going to send them a picture of this plug and demand my money back but if they try to give me a hard time I'm going to have a bigger lawsuit against them. I'll keep you updated, but DO NOT ever leave it plugged in!! read full review »
