I think any new training aid that comes along is worth an honest evaluation. Exercise labs have shown that doing the same exercise in the same way is 'learned' by the muscles in about 26 days, whereafter the value of that particular way of exercise diminishes significantly. That partially explains why you must always increase your reps. Research has also shown that there are precise variations of exercise for development of ancillary muscles. These must be worked isolated and specific. So, it seems to me that if there is a pushup device which aligns things correctly, and has many variations, it will work for a while. Anyone who has a home gym changes equipment all the time for varieties of reasons. I have done literally thousands of pushups between thai pads, and I got bored. Currently, kettlebells seem to be the 'hot' training aid. Before that was that big ball, for core training. A few years back everyone was getting bowflexes and soloflexes. I guess my point is, if you don't want to try it, or haven't tried it, why badmouth it? Someone here will look at it, buy or make one, use it and benefit from it who would never even have heard of it if it had not been posted. Guaranteed.
