Great ball

Ahmed from NJ– Verified Buyer

I own several of these balls. We use them at the gym all the time "I own a boxing gym". I have all the weights Muscle driver makes and they are made very well. They do, however, break after a while of heavy use but Muscledriverusa offer three years warranty on them and they do a great job through Wayfair in sending you a replacement. I highly recommend them.

Great heavy slam ball

Jeremy from Albuquerque, NM– Verified Buyer

I also have the 25lb slammer ball and both of these balls are great. My main reason for purchasing these over other brands is the warranty. I use these on 3/4" stall mats with no issues, very dead hits.

CF from Westchester County, NY– Verified Buyer

This will take a beating and come back for more. Not much else to say, the key with these is durability.

Rickey Ellis from Suquamish, WA– Verified Buyer

This guy is serious. MDUSA 40lbs slammer ball is no joke. First thing you notice is the quality. This thing is meant to take a beating. I know I will get use from it for years to come. Smaller than I imagined, somewhere around the size of a soccer ball. Good feel and grip on the slam ball makes for great training sessions. Very happy with my purchase.

Does what it says it does

Jeremy from Washington State

So far, this ball has held up to the few slams that I've done. Very grippable, and seems to be quality made - Muscle Driver's 3-year warranty is helpful, as well.

Great Slam Ball

Kanway Ng from Brooklyn, NY– Verified Buyer

This slam ball has a good grip and virtually no bounce. The 40 lb ball feels super tough. I would definitely recommend this product to anyone.
