The lowest spring is tough enough to start out with. I'm 63. I was always very athletic. But the last 5 years have been tough. A number of physical conditions have changed me. But, I'm getting back on the right path starting with getting my hand strength back. I've had the gripper a week and in about two weeks, I bet I'll move up to the next spring. Great improvement.

This is has to be a record on how fast these things broke. As soon as I took it out of the box and threaded the handles on, the metal threading broke (they are glued on to the resistance coils) and now it is stuck inside one of the handles.

WOD Nation makes a solid product (we have some jump ropes, excellent) but like others the is no clear way to see what the load ratings are for the springs- yes the higher/tougher ones are bigger but the difference in sizing is small to detect in some. Handles are a little narrow to my liking but workable. Not for beginners, you really need strong grip strength even at the lower level (bought these fir my son). Still, a quality product.

Great grippers set. Work like they should. My hands are apparently a bit soft haha need to build up the finger callus. Good construction and heavy duty.

Purchased this product to increase grip strength. Unfortunately, I was never able to use it. The end of the spring with the threads broke off in the handle on my first use.

It was stated in a lot of reviews that the springs were unmarked and could not tell them apart.Well, if you weigh them on a kitchen scale and set them in order lightest to heaviest then mark them with a silver metallic sharpie as I didyou just solved the mystery.1=100 1.5=150 2=200 2.5=250 3=300

The glue holding the threads to the spring comes loose from tension. Perhaps using a stronger glue or epoxy will work. I am gonna try to glue it back but it sucks to have to fix an item 2 days after receiving it.

Its quality is great, the grip is actually really comfortable (I suggest you to use magnesium for better grip) and the different levels are perfect for progressive overload.The only bad thing is that these levels are not marked so you can't really tell which is which until you use them.
