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.

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.

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.

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

Great idea, great price, wide range of resistance, but the handle is slightly too small.
