Everything we were looking for.

Easy to use. The whole thing is awesome! I watch a guy on you tube who does alot of movements with unbalanced weights on his dumbbells. it was basically between these and the bowflex. I chose MX Because they are more compact and I liked that they used better parts on the inside than bowflex. My wife loves the grip and how quiet they are.

My son-in-law loves the MX55s

I got some great advice from Clark Bantram along with a promo code for the MX Rapid Change Adjustable Dumbbells for a birthday gift for my son-in-law. He absolutely loves them and you can’t go wrong this this system. They arrived FASET and the shipping was also free.
