Query: Was defective so I returned it for credit back.

I bought this for a temporary special application use on my old 1992 Dodge 4x4 untill summer, arrived defective so I bought another brand in this short length also with thermostat control.Some old Dodge trucks like mine,(20 yrs old but runs like a top) are known for the computer contol box going up and not allowing it to start in cold weather.Wrap this around the box, with insulated tape, plug it in a few minutes, fired right up. Just do not leave it sit turned off at the store in cold weather very long.Dodge forum suggested using a hair dryer to warm the box in cold weather untill replaced unless you have a heated garage to do it now.What hair dryer makes much heat sucking in cold air outside in 20 degree weather?? Temporay fix untill spring, then I will replace with a rebuilt preprogrammed computer box available from any auto store.One defective product experience and then I do not trust the brand.
