Rated 3 out of 5 by Onil Fillion from Good but doesn't last & none repairable. The unit itself is well built and does a good job but over time the seals will leak and then the chamber where the micro-switch is fills up with oil. Seal failure is understandable but there's no seal kits available to reseal it so I've had to change it. 3 of them in the last 6 years.

Rated 1 out of 5 by AK1234 from DPDT Switch Deception Bought this because it had a double pole 15A switch. There is only a single pole switch! Called on overnight shipping status, forever on hold, no call back. Item arrived two days later - not overnight as paid!
