Query: Save your money. Its very cheap

I just opened it up. It sort of gets cold and hopefully gets warm.The AAA batteries were dead. The battery lid doesn't fit normal AAA's like eveready.The radio sound is really tinny.The 12v plug was so tight it wouldn't insert until I worked the contacts with pliers to get them to slide.Its made of cheap plastic, the box doesn't snugly latch.Nearly all the label stickers fell off in 5 minutes. The plastic taped logo was bent and never stuck to the latch. It fell off when I opened it. I just threw it away.All the bad stuff said, it was starting to cool and presumably it willwarmer with more time but I haven't even got that far with it.Spend your money on something more useful than this thing.
