Purchased, the gripper and the cannonball, awesome for grip strength training. I also have the grandfather clocks from Rogue great for pullup variation.

Great build quality but the grips are too small for my hands… I wish they were a couple inches bigger in diameter. Sadly, I think I’ll return the product and see if I can find something bigger from a climbing oriented company.

These are incredibly challenging. Pull-ups are exponentially more difficult with this thing. I was trying to get better at pull-ups and improve my grip strength, but I feel like a level 3 game character fighting a level 10 boss. It's crazy hard. There is what looks like some rust on one of my cannonballs where it hangs from the carabiner after over a year of owning them in a climate controlled room, but it still looks and feels solid. 5/5 stars from me. I also got the nunchucks, and they also did a fantastic job of telling me my grip strength is pathetic. I plan to level up, which is fun.

I didn't get everything in the picture. But what I did get. Was great... I love all Rogue equipment!!!!!

Fantastic fit and finish on the cannon balls and straps, no surprise there… Great carabiner of course. I bring these to my big box gyms to show off my forearm strength which has improved dramatically. You could also hook these to low pulleys hi police for triceps and other interesting things. I’m very pleased with this product from ROGUE.

Gripping these balls is super hard! My forearms burn after holding on to these balls for more than 5 seconds. Great purchase!

Love them great for grip strength will definitely buy again!!

If you want to up your grip strength this is what you need! Well built and weighty on its own.
