Small but powerful and reliable

I am very pleased with the Bosch PFD 1037 heating pad 100 Watt. It heats up quickly, is at level 3 really hot and not luke warm and turns reliably after 90 minutes. I have often in use and it is so far no signs of fatigue. The only downside: it's pretty small. The size specification is not specified in the product description, but they have to look for, because to me it is unfortunately only succeeded, after I had received the goods, and I wanted to make sure again. Nevertheless I do not regret the purchase and recommend it further.
