I like the Finnish Ball trainer. I originally bought it to train for King Kong. If you do buy this piece, make sure you pair it with an open top loading pin. The ball is intended to sit vertical rather than being attached with a carabiner. Well constructed and a great price point. I eventually was able to purchase an Otevoima and the welds and paint are much better on the Otevoima, but as a training tool, the Arm Assassins version works great and is much cheaper.

If you're reading a review of a Finnish ball trainer, then you're likely already deep down the rabbit hole of grip toys. Just buy it. Your spouse has already lost track of these things.
Fun key pinch training tool that's considerably easier to acquire than the original from otevoima.
