The Magnum Pro pumps are the best. No issues at all. East Hills Instruments offers great customer service.
The first time I received the Magnum Pro pump I had an issue. I called the toll free number on the pump and within a matter of only a few days the pump was repaired and back in service. They even paid to ship it back at no charge. This experience was truly “quibble free”.
BTW the pump and East Hills Instruments are my new best friends. I wish other companies could learn from them.
Very happy with the (MP-P) pump. No issues.
Really happy with it, never had any issues. Very convenient for remote calibrations.
