PowerBlock Sport 50 Adjustable Dumbbell Set (Open Box)

If I could give zero stars for the stage 3 expansion, I would.I have a Powerblock EXP set (5-50 lbs) expanded successfully with the stage 2 (50-70 lbs) expansion set. Because I have been using all 70 lbs recently in my workouts, I ordered the stage 3 set.Upon unboxing and unwrapping the stage 3 set, I find that both stage 3 expansion units are too narrow to accommodate my stage 2 enhanced Powerblock EXP dumbbells.I will attempt a return for refund.Amazon is terrible with product descriptions. I actually acquired the stage 2 EXP expansions before getting the basic EXP dumbbells set because that expansion set was represented on Amazon as fitting the Powerblock EXP _Pro_ dumbbells—which they do not. (I bought the matching EXP dumbbells anyway because my spouse took up lifting and having two sets is thus worthwhile.)Powerblock has since discontinued this line of dumbbells in favor of a newer (and doubtless incompatible) set. Amazon can’t keep expansion sets straight. Best to look for a different product and to look for it somewhere else.
