Are these things effective?

I use mine quite a bit and it is a good warm up, but I am mainly wondering if there can help you finger picking hand.

Only the blue sky and the green grass
Go on forever in this world
Where seconds feel like eternity
And years pass in blink of an eye
mainly for developing finger strength and stamina.

My husband has had carpal tunnel surgery on both hands. His doctor HATES those things--they stress tendons and can cause / aggrevate CTS and tendonitis.

Dr Phil is correct--practice is a better method here. There are no shortcuts that beat practive and the gripmaster is a dangerous shortcut.
what is a gripmaster?
