Stopped working suddenly in less then 4 months

I purchased this to do my own acrylic nails at home. I have had it just shy of 4 months, so it's been used approximately 6-7 times. Today it just stopped working. No signs that anything that might be wrong, I was in the middle of my nails and it stopped. I didn't expect it to last forever, but I did expect much longer than this.
