Query: Stopped working after 1 year

Stopped working after 1 year, and the actual working time didn't exceed 4 months with a few hours each day... It is broken so fast that the box of it is still kept! So I am going to return it, definitely (Update: of course, I couldn't return it as it went over 30 days after purchase. We found a fuse for replacement and it started working again. However, I still refrain from using it, as it consumes a lot of electricity).
