Query: 2 broke, each after 5 months.

bought one in february. used it about 4-5 times per week for bike tires. first unit failed in july. cost me money to mail it back to blackanddecker. received replacement in august, which broke in november. now will cost more to send that one back again. worked fine until it broke, but just not a product that can function in an everyday use type of situation. I need a more robust compressor with a tank.
