If its anything like this, that we're all the rage - heavens knows why - not so long ago, then I'd definitely give it a miss. I've seen adverts for those little plug-in heaters, didn't know what they were called, but I'd rather snuggle up on my sofa with a blanket, or in my bed with an extra blanket, & a hot water bottle if I was cold than waste money on gadgets that are bound to fail!!
These standing ones that were all the rage, bah humbug, my friend swore by them yet I felt like I was in an ice box even when right in front of it!
