I already knew GD grip trainers are among the best on the market, so this time I decided to properly test the Iron Grip 12. It’s excellent. Once I reach 82 kg, I will definitely buy the Grip 90 model. I would appreciate if you continue developing and selling high-quality products not only for grip strength but for overall upper body strength. I will gladly buy them. I am very satisfied...

Customer Reviews
Taken from the manufacturer's official online store.
View original reviews on the manufacturer’s website ↗The quality is very high and the packaging feels luxurious. Since it is a Korean product, I trust it, I really love it and will use it well.
A big difference compared to cheap grip trainers. Both quality and design are very good. Since it looks nice, it makes you want to use it more and train more often.
I previously used an older Iron Grip which I sold second-hand, and now I bought this new 12-level version. It’s great. The silicone grip feels comfortable and thanks to 12 levels, resistance can be adjusted precisely depending on the situation. If you are hesitating, I definitely recommend it...
The adjustment is more detailed, so it’s great that both parents can use it together.
