I got this to help rebuild my grip strength on my left side and it's definitely helping.I see some people complaining about the grip covers however I am not using this as I prefer them without it as it feels like a fresh barbell.I have only used the standard clamps and I find that they're very good for what I need. I just leave this on my desk at work and use it throughout the day. The build quality is also a lot greater than what I was expecting which is a pleasant surprise.For the price you pay you're getting a quality product that has a wide range given the different resistance levels. I would recommend picking this up if you're interested.

This grip strength set is an excellent tool for improving grip strength, forearm strength, and finger strength.The hand grip resistance of 100, 150, 200, 250LB is a good range from easy to hard. Each hand grip has the pound resistance number engraved on the bottom of the handles. The all metal construction (except for the foam grip pads) should last longer than grips made from plastic. The foam pads were tricky to put on, had to pinch with 4 fingers and slowly pull up. The foam pads get squashed easily and will thin out over use, especially at the higher resistance levels.The are no instructions, so I had to figure out how to use the finger exercise tool:1. insert strap hook into the hole at 5 (easiest), 6, 7 or 8 (hardest),2. put the wrist strap on,3. put fingers in slots,4. then stretch fingers.Because you can use the finger exercise tool for both hands, and all finger slots are the same size, I find the slot a little small for my right thumb.The circle rubber grip ring was good, offers 70 and 80LB resistance.The storage bag is thin, but it fits all the items ok.

The padding for the handles is very fragile. This has been good for me post surgery to keep my hand strength up while I can't lift weights

They don't appear to be marked for you to know which is whichThey do have a difference in strength requirements, I can't vouch for the accuracy.. but I get a nice little pump doing reps at my computer desk with themI don't think they're amazing but if you are wanting to train grip strength then I guess they'd be quite good for what you need & with progression added, depending on your current strength levels

These grip strength trainer set comes with four different weights (all in pounds) 100, 150, 200, 250. It also came with a donut/circle squeeze, one way it's 80 pounds other way 70 pounds. Comes with padding that needs to be manually put on grips, which is a bit tricky and delicate (accidently ripped one). Overall fairly happy with this set.
