I really enjoy using the bed-warmer! Warms up quickly and gets very hot on the highest setting! Four settings for your own comfort. I really like that it is washable (even though I haven't had it long enough to wash it just yet). I don't use the 'ties' that came with it to tie it to your bed. I just put it under the mattress-cover, which keeps it in place. Wish it was a bit longer/bigger though.
