i still enjoy using the mq most. sometimes get issues though as u said, and for a relative noob to these, finding out what the issue actually is.....would be tough. for me...mines will vent out the valve every now and then. its not a huge leak....and it doesn't bother anything, but it's there and it irritates me when it's happening. rechargeable batteries would solve most battery problems.
i just messing with that mech now because i want something with an auto auto trigger. to do that to the mq would be a bitch. main thing for me is.....the mech provides a solid back up pump to the mq. just gotta make sure the stroke is light....cause after pumping the mq everything else seems heavy
