Was a bit worried about putting this together after reading another review but, it wasn’t hard. Pair of pliers and a socket set is all you need (two people will make putting the body together easier, but I did it by myself). It feels well made and sturdy. I had a little trouble getting the app to work (it wouldn’t let me make an account and the videos wouldn’t show). But, that’s fixed by scanning the code right on the front of the equipment. I haven’t used the app yet, I used another app (when I couldn’t get the right one to work) that calls out combinations. Overall, I VERY happy and satisfied. Only thing, DAMN this thing is expensive!
