We have been using the original Magic Bullet forever to make our morning shakes that we'd take on the road, but the stupid plastic tabs on the mugs kept breaking. We decided after spending so much on replacement mugs and watching the prices go up, it was time to upgrade. The Pro seemed like a good option, but unfortunately we didn't think it all the way through. First, these have the same design of plastic tabs, albeit they might be a bit thicker, but I'm sure they too will break. The most disappointing thing about this set, however, is it is NOT made to take on the go! Look carefully at the picture: you have a choice of a handle OR a lid, and the lid SUCKS! Already spilled twice with little protection. And the mugs don't fit into any cup holder and are nearly impossible to carry with one hand while juggling a briefcase or purse.
If you intend this only for home use, it's great - much better motor and such. Otherwise, for our use, we should've stuck with the old bullet and saved our money to buy more mugs.
