Query: Burned out after a years use

I only used this once a week to keep my mountain bike tires inflated. It works well for awhile then it starts to make a loud rattling noise, and takes a long time to work. The gauge is a joke, it is 10 psi (pounds per square inch) off. After 6 months it will operate at 50% power then one day it will just die & nothing but a lump of plastic & metal. I took it apart thinking i could repair it but not really worth it, if the motor goes out then thats it. I dont expect years of use but only lasting a year is not right. If you use this to inflate car tires or a raft or something you will get even less than a year out of this....I do not recommend & I will not be buying any Bonaire products in the future.
