I've had the Perfect push-up for a while, if you buy one they have a whole sheet for different programs to help increase your push up count and fitness.

Its a great body weight exercise, and when you just start out you'll have a good burn for a day or two in your shoulders and inner chest.

The difference is the twisting motion and the elevated bar, like others have mentioned. If want to buy them for increasing push up count, I'd recommend just doing push ups without equipment (the perfect push up wont make a huge difference in your push up count like I hoped, I actually fell off my usual count when I used only the perfect push up).

I will usually do my standard push ups, followed by another set. That method works much better at increasing my standard push up count.
