You asked for opinions and then you wonder how people can have opinions about something they didn't ever try?
Opinion:
A belief or conclusion held with confidence but not substantiated by positive knowledge or proof: “The world is not run by thought, nor by imagination, but by opinion†(Elizabeth Drew).

I think there we plenty of opinions here. You just didn't get the one you wanted. And if Harold Poole would recommend it. And you like him.. then it's that good enough?
I had a Soloflex (same concept machine) when I was 18-20 and
I LOVED IT. Great workout machine. No I didn't gain much size. But it was sweet for fitness and getting in shape and defined and getting some muscle tone. My option of those machines is.. if you wanna workout at home, you are new, you don't have a spotter and you don't want a full gym or no room for a bunch of free weights.. it's an excellent choice. It's not a second best..
it's perfect depending on your exact situation. You.. being a 14.5 year old linebacker.. it's okay. Does it mean if you do your 420 lbs of resistance you can go into the gym and bench 420 lbs? Don't think so. Will it help you out.. with your sport? Yes. Will it be the most efficient way of doing so? No. Is that bad? No.
Momentum shouldn't play a part. It's not like I go into the gym, bounce 315 lbs off my chest.
What is different about those machines is on the way down there's esistance along with the up. That's kinda cool.
So to answer your question. Everybody gave an opinion. And now I gave mine.
