Very clever design. It allows you to align the rope in different directions so you have many grip configurations to train on.
I like the carabiner too and it has a cool carry bag.
Very useful device considering its size - super compact. 3D printing around the edges where the rope runs through is beginning to fray after ~10 uses but shouldn't break. Great surface feel and good for both hanging and lifting.
These are fantastic. I really like the different angles.
Had a small hiccup with ordering but they handled the situation swiftly! Legends👑
Really great. A wide variety of possible gips, all of which are comfortable. Easy to set up outdoors for warming up or to add weights in the gym
We use the Rock ball for pull ups and grip strength. Something different and has so many functions, sick of the modern wood grip balls that you find these days so was really stoked with the Rock Ball.
I like the magboard mini and hope it lasts a long time. It seems solid, compact and well shaped.
It's light and comfortable to use.
I was impressed the design and how nicely in changes from mono to two finger pocket mode. I will be using it with a dynamometer for training at home.
Great little lifting edge packed with so many different features. Small, portable and made out of biofriendly materials so great for travelling overseas. I really like the addition of the unlevel edge to allow for more even weight distribution when finger training.
