Definite A+ for this over-the-door pulley system. No "cheaply" made parts here. From the over the door heavy grade (aluminum) I'm thinking to the cord itself or the metal pulley (not plastic where others are!) and even the wood handles, you don't have to worry about something breaking when using correctly. Since my shoulder replacement I've used this for a couple ofon the with great results and it still looks brand new! Very definitely recommend this product, don't let the price fool you! I received way more great quality then I expected!

Excellent. I am using this to restore Range of Motion. I push the limit exactly as I wish. If I want resistance, I control that as well.
It's small, doesn't take much room. Do adjust the rope for your ram length.
If I haven't used it and am walking past, I can stop, use it for a minute and leave. Can do that several times a day, very convenient.

I bought this for my wife because she has a shoulder rotator cuff tear and her doctor recommended exercises with pulleys. Works just fine, slips over a door and the quality is good. Price is very reasonable and I would highly recommend this for anyone who needs Occupational Therapy on their shoulder.

Simple, affordable and effective, this little contraption is wonderful for those experiencing limited range of motion in the shoulder girdle. It hooked easily and securely over the door and is remarkably unobtrusive. It's nice to find something affordable for home rehab exercises!

I had rotator cuff surgery this summer and have been going to physical therapy to gradually regain my range of motion and strength. The PT has a similar setup as this pulley system, only built-in and probably sturdier, and it helps a lot so I bought this to use at home. Added to all my other stretches and strength exercises I'm seeing a huge leap forward in returning to normal use of my shoulder. This pulley system is easy set up and to use -- just put it over a door and adjust the cord length to suit, grab and handle in each hand and start stretching. I leave mine set up on a bedroom closet door all the time and use it several times a day. Feels wonderful to stretch. My physical therapist is the one who told me to look at Amazon's offerings and not mess around with buying a pulley and making my own -- the pieces cost as much as buying this all ready made.

Do be aware that this isn't intended to hold a lot of weight, just the weight needed to stretch your arm, but it's plenty sturdy enough for that.

EDIT: Thought I ought to mention that I'm 5'3" and when my shoulder is extended fully upward (hooray!) I can touch the pulley itself. Taller people will most likely need to rig it up higher than just hanging it over the door.
