Projectile launcher almost took me out (broke on first use)

So apparently the handles that attach to the resistance band are held in place by a little rubber ball inside the tube. Unfortunately, the ends of the tube are open. Why aren't they sealed shut? I tried doing one squat, as directed by the provided instruction manual, and the handle broke off and the little rubber ball shot into the floor and almost hit my foot. I'm 6'2" which isn't too freakishly tall imo and squats are in the guide book! This is a dangerous design flaw. 0/10 recommend! It might still work for the other exercises that don't stretch the band as far, such as half rep bicep curls, but I wouldn't risk it unless you like getting shot in the face ;) I'm sending this piece of garbage back asap and getting one of those cheap ones without the handles or the hidden bullets.
