Fit Quip, 20 to 90 lbs. resistance.  This is so great to have, I use one similar at my physical therapy.  But this one is so much better.  Easy to adjust the resistance. My husband can go pretty high, but me I have the lowest and it still a struggle on my left hand, due to surgery.  I will be using everyday to try to get my strength back.  Easy to clean, just wipe down with a damp cloth.  The handles are well made and very comfortable.     Thank you for allowing me to try your product  I recommend this product. Disclosure: I received this product at a discount in exchange for my honest review.
