Bought one of these for my mother, who has mobility issues and often feels cold when sitting. She loves it as it retains the heat for so much longer than the wheat bags. Was so impressed I bought one for myself as I have Raynauds issues with my feet, so will use it to warm my feet when I am working in my home office. The specified heating time does not feel like it heats it up fully but it actually does - it gets warmer as you hold it and stays warm for a long time. Highly recommended.
Ordered online, delivered in a couple of days and have nothing but praise for the service! Micro hottie is an excellent product, keeps my hands lovely and warm when traveling in the car and heat holds for hours! Would thoroughly recommend it to keep warm.
