While I had previously always refrained from electric blankets, because I thought it (compared to traditional hot water bottles) always for "bulky" to and dangerous, I could fully convince this little heating pad Bosch. Bundled the device is less than a 1-liter water bottle, light as a feather and ready for immediate use in case of doubt. It usually takes only 1-2 minutes until the heat is felt. Shortly thereafter, the device then heats constantly on one of the three selectable temperature settings. Another practical feature is that the pad is very shallow, so you can use it very versatile (eg as an underlay under the body when winding around a limb or as a neck roll). Overall, a first class product at an affordable price.
