KDG Hand Grip Strengthener 2 Pack Adjustable Resistance 10-130 lbs Forearm Exerciser，Grip Strength Trainer for Muscle Building and Injury Recovery for Athletes

These hand grip/forearm exercisers work very well. It’s nice to be able to increase the tension and have the counter.

To summarize my review: This is a stress ball on steroids. If you ever feel stressed, this product will do wonders for you no matter how big, small, strong, or normal you are. This product will be integral to your daily life. It's highly adjustable and fits snugly no matter the hand size, and the grip is comfortable. Buy it.Let me warn you: I am lazy. I hate standing, I hate moving, and I hate anything that requires any form of long-term physical discomfort. I do however love to work out, I love to walk on a treadmill at max incline, I love lifting weights, and I enjoy a good sweat and massage. So I understand this seems paradoxical but it's really not.So imagine my surprise when I don't even have to get my big ass off the chair to get a good workout going!! No need for that rubber band, no need for barbells, no need for any form of effort beyond picking up some clickers and clicking them. It's easy, requires no preparation, and feels like lifting weights.It has a counter, the counter is pretty bad. It isn't aligned properly, it only goes to 99, and resetting it is a pain. So I don't plan to use it. Also, the metal spring on it is perfect. It is made where you can change the position of the spring which increases the resistance up to 130 pounds. However... this is not exactly true.I can easily max this out and do the 130-pound resistance however the problem is the thing starts to bend and the grip starts to move inwards and doesn't properly touch the other side causing the metal to bend. If you max this at 130 pounds for the long term, it will eventually bend and break. However, it's pure metal and it will take some effort to break. The grip is held against the spring by two large metal rods. So it's not like this product isn't very durable, it's durable.If you are like me, lazy, unmotivated, and just wanted to workout because you enjoy the feeling, and love to pick something up and build strength, this is for you. The whole reason I bought it was that this was the best bang for your buck, there are 2 of them for 20$ and I don't like having to switch it between my hands. I am that lazy.But, I do burn about 2000-3000 calories a week on the treadmill and other machines in the gym so this is a perfect little device for letting out a bit of energy while you are in your recovery period. I do wish it was capable of withstanding more than just 100 pounds but for me 100 pounds is perfect. I am 330 pounds with 24% bodyfat (around that.) and I can probably bench 350+. So trust me, if this works well for me, it will work extremely well for you.

The mechanical part is solidly build and should last for years. The adjustable strength part works well. Excellent for rehab physical therapy. I have medium size hands and they fit well. But you may want to look for a bigger one if you have a big hand. The only negative is the digital counter. It is so flimsy that I doubt it will last long. It is also difficult to reset the counter. Have to make several tries.

Nice and very easy way to work forearms. Nice quality. Wont easily break on you; can last years.

After several years at the max setting of 60kg, the spring on one of mine broke. I guess they aren't made to be used at max setting for a long period of time. I highly recommend these but they need to use titanium.

They definitely serve their purpose and are easy to adjust as needed. The counting mechanism is quite noisy though and the numbers on one hand don't line up. I chose to purchase these for the adjustable resistance, but it is kind of hard to gauge where you have it set because there's only a tiny graph and no arrow showing where you have it set. I also have small hands, and the higher resistance you set, the gap increases, so it becomes harder to hold/squeeze. (Obviously it takes more strength to squeeze the higher resistance you set, I'm only referring to the gap and how difficult it can be to wrap your hand around to squeeze it if you have small hands.) So this is a great starter piece, it is quite durable for the price, and pretty straightforward.

The front handle is long enough that all 4 fingers can get a grip. The rubberized surface keeps my hand from slipping/rotating as I grip down. Plus the tension is easy to adjust, and the built-in counter is a plus.

these are ajustable so it's easy to improve your growth in strenght and have a built in rep. counter, cool!
