i bought this as a 9kg ball. it’s slightly heavier as it’s actually 20lbs. it’s great tho v happy with it

Arrived well packaged and slam ball is as described.Lovely vibrant colour and the ball has a good texture to help with grip during a workout.I like that the ball is filled with sand and not solid like a medicine ball as I find this better for the range of exercises that I do.I personally think it is good value for money and happy with purchase.

Really good for home workouts

Ball does the job but I found enjoying that sand inside is moving. I used many different exercise balls on the gym and I prefer the one with equal weight.

Use it in my garage it's it's bit heavy but that my bad nothing to do with manufacturing, been using it relentlessly OUTSIDE and not a blemish on it brilliant quality

Very poor quality. Advertised as a medicine ball. This is not a medicine ball this is a slam ball. Lusting does not say will require inflating. Sand inside is not half way up as per the image portrays. No after sales help available. Save your money and shop elsewhere. Amazon, do better. Stop letting sellers list inadequately.
