I love the pro jr. Definitely one of my goto models when I want to have a ride. The ONLY downside of it for me is that the tabs can be a bit 'sharp.' While they are obviously not sharp meaning they can cut you, they can put a lot of pressure on a very small area which can cause some discomfort if you have strong pc muscles...I've remedied this with some silicone nipple toys that I put over the tabs sometimes to 'soften' them, but I think a pro jr with the round 'tabs' that are on the full size progasm and maximus would be a nice improvement comfort wise.
