The Adjustable Hand Gripper, Double-Spring Version

I own all the COC grippers and have owned the Ivanko gripper. I gave a friend my Ivanko gripper once I got the COC set. Big mistake as even with the in between COC grippers it's hard to get just the right weight. Both the COC and Ivanko grippers are excellent. Let me write about the Vatiz gripper now. First off it comes in very nicely packaged from the shipper and Vatiz. Shipping was very fast. This gripper is a beast. It is heavy and very well made. Very smooth movement. Has the same grip angle as a COC gripper. The handles are slightly thicker, but not by much. Very easy to adjust. I'd take this gripper over the Ivanko any day of the week, though I'd still buy the COC as they are the standard for testing your grip strength. Yes, it is an expensive gripper and worth the money period. I'll be using this along with my COC grippers. This gripper is just now making its way to the USA. I tried researching it before buying and could only find one review in English other than Amazon. Seems to be very popular in Russia. Anyhow, I'd buy this gripper again with no second thoughts! I am very pleased! I added a picture with a COC 2.5 on top of the gripper. The handles on the Vatiz close tightly together.

This is a very well built adjustable hand gripper. Body is made from stainless while the handles are made of aluminum. The knurling is not very aggressive and requires the use of gym chalk.Pros: Sturdy stainless frameMany adjusment levelsComes with 2 springsVery smooth actionNice packagingWorth the priceCons: Handle knurling could be more aggressive (may not be a con for others)Whether you're a beginner or an expert, this is definitely something worth adding to your collection.

This thing is seriously well made.Cons:1) It’s huge! It’s the size of a regular gripper with another gripper above it turned upside down.2) It’s way harder to squeeze than my other grip trainers. I don’t know if those are wrong or this one is wrong as far as the resistance. I have 100, 150, and 200 pound grippers. The Vatiz one is harder on the lowest setting (supposed to be 60 pounds) than the 100 pound gripper. The setting that’s supposed to be around 125 pounds is as difficult as my 200 pound gripper.Neither of these issues take away from that fact that this gripper works really well. Maybe bruised my ego a little bit because of how hard it is, but that’s really the point of training.

Everything is great about this gripper except the knurling. It’s too smooth and will slide out of your hand on the higher settings (6-6 and up).I really wanted this to work for me. Was using this to bridge the gap between the CoC 2 and 3, but it just slides too much.

Used and currently using this item to regain hand and forearm strength after rotator cuff surgery. Spend three months with an arm in a sling. This item helped my strength in the inactive hand and forearm quickly. It is solidly built and will last a lifetime. The packaging is nice and I kept it for storage of the device. The knurling is good and gives a positive grip for a single spring. Once you move the spring toward the top or add the second spring it would be wise to get some chalk to aid in grip.

I haven't analyzed whether this works better to increase grip strength in comparison to other grippers - I have several different types. But, for me, part of the value of a piece of exercise equipment is that it feels right - makes the exercise more enjoyable. If I find myself looking forward to using it, I use it more often. The Vatiz just feels perfect for my hands. I have a few other adjustable grippers. The only one that fits my hand this well is the Baraban, which I reserve for doing negatives at this point, due to the attachment that they provide for that purpose. But the vatiz - I just love picking it up and using it. Really an excellent piece of equipment.

Was almost impossible to adjust the Springsteen as a result the item was returned

This gripper is seriously amazing. Forget buying multiple grippers at $15-$25 a piece (one for warm up and buying new ones as you get stronger), this in the only gripper you'll ever need. The best part about it is how many incremental weight settings it has. The typical 50 lbs jump for each standard gripper is a little excessive but this gripper lets you go up in ~12 lbs increments. The product itself looks great and is built as solid as can be. You won't regret buying this gripper!A big difference of this gripper vs others is that standard grippers have an uneven pull throughout the motion; it's easy at first and only really gets to its full resistance within an inch of a full close. The Vatiz gripper has even resistance throughout the entire pull. With a standard gripper, the bottoms of the handles will touch but there will be space along the rest of the handles that increases toward the top. With the Vatiz gripper, the handles touch throughout the entire handle. Both of these combine to make the Vatiz MUCH more difficult to close for comparable weights but it also means a more thorough forearm workout.Edit: After three years of moderate use the spring snapped.
