USI UNIVERSAL Steel Heavy Duty Hand Grip Strengthener, Wrist & Forearm Hand Exerciser, Finger Exerciser, Hand Gripper Grip Strength Trainer (Silver-300 lbs/150Kg Weight Capacity)

This is genuinely 300lbs, (I had doubts but man this is the real thing)there are some video reviews about this product that shows that it's RGC/ weight is less that 300lbs but i actually purchased both usi 300 lbs and udki 300 lbs (old black one). The usi one feels much harder and has more handle spread. Knurling is also better on this usi one. Build quality is superb and would easily last a lifetime. If you are an absolute beginner you can go for lower weight ones but for enthusiasts this feels like a standard international product. This is a real review you can trust me, I also saw the hologram on the box with product ID and stuff so i know it's the real product. This will definitely feel harder than other 300lbs grippers due to it's handle spread and thickness, I actually like it because in real life this would actually be usefull as most things you will grab won't be thin and designed to be grabbed (uneven, rough and thick). So it also puts good amount of calluses on your hand. I will post pictures compared to udki 300lbs on the left, you see and decide. I like both, udki to more reps and comfort and usi for short intense practice when I am ready. Peace ✌

I thought it would be the same as other gripper but when i order it i could barely move it to halfway. So now i have ordered the 200lbs version (the 100kg one). Quality of the gripper is really great. ₹858 was worth it

Solid Hai Bhai .....Bahut Achha Training Hota hai....Nice product......

This product is great but only for someone who has great forearm strength to begin with. This is definitely not for beginners. I got a decent forearm strength but can't even close it once .

Excellent and "sticking to basics" product for improving hand grip for interested persons and gym fellows. It takes real strength to squeeze it. I am yet not able to make both handles meet, haha. The grip handles have good knurling. Works best on forearm muscles. Rated for 300lbs.

Good one

Very heavy strong durable product. I just brought 300 lbs one .I barley could squeeze an inch it’s very challenging if you will be used to it you gonna crush must of thing with that strength.Go for it .

I bought it, and it amazed me with its quality but, the metal spring part is a lil bit connected to each other that's why 3 star rating instead of 5, I think it's paint connected to each other but it might me metal so I might have to replace it Edit: it's metal connected to metal, don't buy if you don't want headache
