Final Verdict and Review

These dumbbells priced almost twice than the world’s best Bowflex SelectTech Adjustable dumbbells with are much lesser with weight range so I won’t be picking StairMaster over Bowflex just because of its adjustment system and cool design. The next issue is obviously the durability.Whether in gym or home, there is a time when you get very motivated and on the run with your sets and reps there is a chance you can drop the dumbbells for a time or two and because of the plastic components attached with the StairMaster you can’t do that act. Making these dumbbells very easy to break.  The handle was very comfortable which was fitting very easily and tightly on my hands and was giving me a natural dumbbell feel too. That was very nice for me yet the balancing and adjustment was one of its best features.
