Yes, I recommend
I bought this for another teacher in my department after years of continued great service from the inertia ball I have. The inertia ball that arrived is exactly like the one I previously purchased, but does not match the one in the photo. Here are the rough measurements: ~1.75 kg, ~78 mm diameter, the eye hooks are only about 13.5 mm outer/6.4 mm inner diameter. This sphere works great for inertia demonstrations and as a pendulum demonstration when hung from the ceiling.

Thank you for sharing. We're happy to hear that these inertia balls are consistent with your previous purchase.
"Item sent nothing like photograph" - The inertia ball that I was sent is too small to be used for physics demonstrations. Also the ball sent looks nothing like the one illustrated.
