KIBTOY Hand Grip Strength, Metal Grip Strength Trainer No Slip Heavy-Duty with Adjustable Resistance 50-150 lbs, Forearm Exerciser for Muscle Building and Injury Recovery

This gripper is great. At lighter settings the spread of the gripper is pretty wide, however it is pretty standard practice in the grip training world to use the off hand to pinch the bottom a bit to help get the proper grip on your training hand. You've really got to make sure that you've got the handle screw tight after adjusting but it's not difficult to do. I bought the single but for the price would recommend the two pack. One of the vehicle and one for home. Must have for grip dorks.

Works well for what it is and good for the value for the adjustable setting on it. Needs some form of catch on it for both correct weight measurement as well as locking the handles in place, doesn't matter how you tighten it down it will still slide some and break tension easily.

Nothing more to say. Been using for a month without any signs of deterioration

The Kibtoy grip strength trainers are decent.On the plus side, I like that they're adjustable. The handles can be used bare, as they have textured grips, but you can also use included rubber grips if you want. The grips do make the grip pretty wide, so if you have smaller hands keep that in mind.I've been using them for about two months now and they show no visible signs of wear.There are several drawbacks to these trainers, however. First, there's some obvious quality control issues. For starters, the two trainers I got - that came out of the same box - have vastly different number markers on them (see picture). One appears to be a light etching, while the other is stamped in to the point of being unreadable.The handles also don't hold their adjustment well, and frequently slip. If you find a setting you want to keep, I suppose you could tighten them with a pair of pliers, but it kind of defeats their adjustable nature at that point.Finally, the markings on the handles are consistent - 50 pounds increments spaced one centimeter apart, and identical between the two trainers - but I'm not sure that the force required to flex them is what's printed; the 50 lb. mark seems like it requires less force, while the 150 lb. mark definitely does not require three times the force of the 50 lb. mark. For someone like me exercising casually, this isn't a big deal as I just adjust to what is comfortable, but if you care about numbers you may want to look elsewhere.

Great value!

Unfortunately I was not strong enough utilize this product to help recover from a stroke. I had difficulty returning for a more realistic item for my strength capability.

I have a 16 yr old basketball player and a 14 yr old swimmer that really like these for developing hand/forearm strength. Great for watching TV and exercising at the same time, or for long car rides. Well built and seem sturdy. I definitely recommend.

I have issues with my hands as far as arthritis and joint pain so I thought these hand strengtheners would be great to firm up my grip. Upon arrival trying to change the weight of the grips based off of instructions they came fully out of the metal hand grips. After trying to lock them repeatedly they are unable to be locked. I wouldn't recommend this product.

An sich ein super Produkt aus hochwertig verarbeitetem Material. Leider eher für größere Hände gedacht, was in dem Fall aber kein Problem darstellt

Yes with the grips on they are a bit sturdy , I use them without grips much better , yes they might squeak a bit but nothing to bother with good value

Ben fatti ma per la mano di una donna (io porto un 6 o s come misura di guanti)sono grandi non riesco a stringere

Ottimo prodotto con varie misure di forza

Die Verarbeitung und das Material der Polster sind gut.Das Verstellen des Widerstandes gestaltet sich problemlos.Das einzige Manko ist die Spannweite. Heißt so viel wie: Man muss es erst ein wenig zusammendrücken, sodass es in die Handfläche passt. Grundsätzlich kein Problem, aber für das schnelle kurze Training zwischendurch nicht förderlich.
