I bought the Infantino Twist and Fold Activity Gym the last time it was offered as a side deal. I needed a replacement for the shabby, second-hand gym that we had that didn't fold up and fit so neatly into baby's closet.
I've been very happy with it, and better yet, so has baby. I only have a few minor complaints about it.
First, occasionally one or two of the leg supports will "pop" back into the twisted position. It's annoying, but doesn't appear to be of any danger to baby at all, so it's something I can live with.
Second, the little velcro ties that keep the whole thing neatly twisted up for storage could stand to be about an inch longer. It still works great, but the shortness of the ties makes it more of a two-hand operation...with a baby, it's really nice when things can be done with one hand.
Third, and sadly, my dog also really likes the gym. Unfortunately, he got a hold of the little mirror that comes with it. This is in no way Infantino's fault, but, after contacting the company, I was extremely disappointed to find that there is no way to get a replacement piece.
