We bought this as a Christmas present to ourselves - something to snuggle with on the couch while watching TV. Due to an unusually warm winter in our area, we didn't break our blanket out until late January or early February. Even then it didn't get used every night. At first the blanket was amazing! Warmed quickly, stayed warm. So warm in fact that we usually turned it down from a 9 setting to a 6 - or even 4. LOVED my blanket.
About 4 weeks after we first used, the blanket didn't seem to stay as warm. We started keeping it on 9 and even then it was just like using a regular blanket. Now it's the first week in April and the blanket is dead. So, in short, the blanket had a life span of about 2 months. Certainly not worth the money.
