The Gripzilla Tornado stands out with its unique ability to provide 3D movements that simulate the natural biomechanics of human joints. It activates all forearm muscles, offering a more comprehensive and effective workout compared to traditional grip training tools.

It is particularly effective for rehabilitating injuries such as carpal tunnel syndrome, tendonitis, tennis elbow, golfer's elbow, fractures, ligament tears, and post-surgical rehabilitation.

Squeaking noises can occur when metal parts come into contact with each other, which is normal. The solution is simple: apply a single drop of oil, such as mineral oil or chain lube oil, to the affected area. This should eliminate the squeaking and ensure smooth operation.
