Too small
Have a bunch of SMAI kettlebells, which are GREAT, but the slam ball is a complete fail.
There's no size or dimensions information on the website product page so I scrolled down to ask a question. The website "AI" help sends an automated email to me asking if I really want my question answered by the SMAI product team. Seriously?!?! (see photos)
I have a couple slam balls from other companies and figured instead of wasting my time potentially dealing with more AI nonsense, the slam ball had a standard 11" diameter. Never seen a slam ball heavier than 30 lbs with anything other than 11" diameter.
Immediate buyer regret when the slam ball was delivered. The delivery box was too small. Fully inflated the ball and took a measurement. 31 1/4 " circumference translates to just under 10" diameter. You may think 1 inch is unnoticeable, but it is. See photo for size comparison. For reference, I'm slightly smaller than average build - 5'5" and 165 lbs. Anyone of average or larger build will probably also think the slam ball is too small.
The only reason this gets 2 stars instead of 1 star is the build seems decent and on par with my others.
Unfortunately paying for return shipping makes no sense, so am going to have to try and sell this on the used market.

They look pretty cool and the grip is perfect. The only thing is the white is kinda yellowish on the printing.
