Honestly, I look down on this kind of equipment.
If you're willing to spend 50 dollars, get yourself a good dipping belt and do weighted dips. That is, if the goal is getting more of a challenge.
However, if you just want to do pushups, then stop trying to buy crap and just do the ****ing pushups. There are many pushup variations that are designed to make pushups harder without you actually needing to use anything extra. This kind of stuff is born out of consumerism, laziness and idiocy.
Now, some people have wrist problems so they can't do many pushups flat with palms flat on the floor. If you've got wrist problems, then try different variations (on knuckles, on bars or whatnot).
