Excellent grippers! Recommend

La textura es áspera y no se resbala. El único problema puede ser el tiempo, pero es entendible cuando vienen de importación

I normally wouldn't be interested in hand grips as every one that I've seen is made of rubber or cheap plastic and usually have no grip either. But I saw these were metal and actually had knurling. The same exact kind you would find on the bars at the gym which is really cool. The metal is pretty durable so far though time will tell how well it holds up. They feel very sturdy and premium. Which is always nice. What I particularly love is the grip. It's very detailed and feels exactly like a barbell which is what I wanted. Every time I use it at work it feels like I'm back at the gym. Doesn't slip. Feels great. I do forearm exercises at the gym but I wanted something I could use outside the gym that was portable so I could make use of my downtime. This alone won't blow up your forearms. You'll need to also do wrist curls with a dumbbell. This is more for grip strength training only. If you are like me and deadlift without straps you need to make sure your grip is on point. This definitely helps.

Speedy delivery & packaged just fine - especially good that they can be posted through the letterbox. I’ve had all sorts of different grippers over the past couple of decades, almost all pretty cheap & very, very easy to close repeatedly. A couple of years ago I bought a ‘heavy grip’ that was a cheap imitation of the Captains of Crush. It was apparently rated at 200lbs, which I couldn’t quite close fully, so I was looking to find something to help build up to it. I must admit that I was drawn to the CoC grippers via some YouTube videos where they were testing folks grip strength (Jujimufu, Brian Shaw, Brian Alsruhe...) & decided to go for the CoC #1, since I figured I was already close to getting 200lbs, so 140lbs should be easy... Guess again. Well, I still loved the quality of this gripper, so almost immediately ordered the Trainer, to give me a lighter weight to warm up with. Pleased that I could then close that (100lbs), but decided to round things out by also ordering the Guide (60lbs), as my wife & kids were also now interested in getting their grip stronger, but they could hardly budge any of the heavier grippers. The lightest two were a bit squeaky, but that was soon remedied with some 3-in-1 oil application. We’ve also now got some really light squishers & finger bands for extensions too Overall, we’d definitely recommend the CoC family of grippers.
