I used them and by far the worst company I have ever used toilets are always dirty Jeff, the supposed to be owner is a horrible person to run a company. I would have to say the only joke better to Jeff being an owner is the management some guy named Jason what kind of manager is this you ask him to fix something and he can't make a management decision on his own. I strongly suggest not to use MMG there are plenty better Chem Chem, united, Moore are just a few I have called also they have more to offer. Don't waste your time. ..
