There a failure because the distributor won’t service them. You ain’t sending that back to America for a yearly “recommended” proportioner recalibration .
Im not sure I have what is called the pro cube but I have a booster that is powered by a gas engine that is in a box like that.
What have you heard about overseas?
I would say they have issues like anything else out there but overall I like mine. When running properly it’s incredible.
The accessibility is definitely a challenge sometimes but get used to it after a while. A forklift is needed anytime anything goes wrong in that box. Only issue I have is you can not just pull the canister of the booster off with mine; have to take the pump out, which requires taking 4-5 other steps before you get to the pump. A 20 minute job takes at least 2 hours to do. I do like it though and Paul was great helping work out the kinks early on.
