AWESOME!...and I dont say that often...
I doubted this donut at first but bought it anyway as just another knick-knack to lose, doesnt look fancy and is inexpensive. WELL, that was last year 2006 I believe, (time flies...) OK, buy this for [$], buy 2 or 3, keep one in the car and use it when the mood hits. DURABLE, GREAT STRESS RELIEVER, ACTUALLY WORKS hands,4arms and even biceps,(fast toning!) and it is fun to see quick imprvmnt. Also, the donut can be worked slooowlyy or quick. Verstile! Highly recommended arm trainer/driving exercise, doesnt impeed manual transmission shift. Buy it, try it, love it or leave it, its [$] and still looks brand new. Simplest "tools" always most effective. (for some of us.) Good luck!
Awesome little trainer
This little guy is awesome and the price is right. I picked this up at my local REI because of all the good reviews and I was not disappointed. I started climbing (indoors) a few months ago and found that after a couple hours on the wall my forearms would be totally gassed and I could barely grip a water bottle, much less a hold. I picked up this trainer and now I do them in the car on my way to and from work. I started out being able to do 100 reps per hand. A few months later and I'm up to 180 reps per hand. Now I can go to the gym and climb for 3 hours straight and my forearms are fine. The grip endurance used to be my weak point. Now, because of this trainer, those days are past. Now I need to toughen up the pads of my fingers :) Bottom line: This forearm trainer is cheap, durable, and effective. Buy it.
This thing is awesome!
Bought one of these, figured for the price if its a gimmick I'm only out a few bucks. Turns out, its perfect for pre, mid, and post-climb workouts. My grip is stronger, my cramps aren't as bad, and its easy to carry pretty much anywhere. I might pick up a few more, keep one in the car, one in the office...
Don't Judge a Book By Its Cover
The product is just a plain blue donut, doesn't look too fancy and the price is reasonable as well. Use it in the car, at home, at school or whenever your bored. It provides a good workout every time you squeeze it. Also a great stress reliever, and sometimes a good anger reliever as well, well for me. It is lightweight and can easily be packed in your backpack and be taken with you anywhere you go. One thing i hate about it is that it smells too rubbery, but not enough too notice it. It can only be smelt when you bring it near to your nose to smell it. And it leaves the same rubbery on your hands after using it the first couple of weeks. No a very big negative. Bottom line, The product is inexpensive, light, nothing too fancy and does the job!
25% Grip Strength Increase!
Each year I have a comprehensive medical / physical evaluation through my employer. One of the tests is my grip strength. It is taken annually and over the last ten years it has averaged 55kg. I started using the Black Diamond Forearm Trainer about three months before my last physical. I did 15 reps on each side for three total sets, five days a week for three months. At my last physical, my grip strength had increased to 69kg!! I am not a climber and bought the Forearm Trainer for the sole purpose of increasing my grip strength and improving my forearm definition. It has definitely worked for me, and I highly recommend the trainer for anyone looking to increase strength and / or improve the look of your arms.

Timeless classic
This is an excellent, durable trainer that you can take with you wherever you go. On the plane, in the car, in class, or whatever. Just throw it in a backpack or carry-on bag. You can get pumped pretty quick with this ring, and it's going to last. I've had mine for 3 years and it hasn't really changed.
Best forearm/grip trainer out there
I got this and a gripp medium firmness ball. This little donut works very well as a grip trainer as well as a forearm trainer. You can work pairs of fingers, all at the same time, or just a pinky. I would say that for the price, this is a great product.
Smells awful, but fun
In the words of Ron Burgundy, this thing smells like pure gasoline.
Great work-out tool
Great tool to work all around hand and forearm strength. Starts out tough to use, but don't give up on it, you will improve. A must for any climber who is getting serious about the sport.
Could be stiffer
I can flash most 5.12's and cant remember the last time I fell off a 5.11 when I wasn't pumped out. I didnt boulder much until recently but am into V7's...all indoors. I usually climb about 3 hours a day 5 or so days a week. I picked this ring up because it was half the price of the other trainers and I wanted something for when I'm on vacation and can't climb. Putting it in my palm i don't think I could wear out my hands/forearm. If you use your finger tips instead of fully gripping it then it's decent resistance; good if youre going to do a bunch of reps. But I think the best use is probably training 2-3 fingers at a time. Then it's pretty good resistance and I could see it giving a good pump. I can crush it using my pointer and middle finger but it's too much for my ring and pinky to handle. Hope that gives a good idea of the resistance.
