IronMind Captains of Crush (CoC) Hand Gripper - The Gold Standard of Grippers | The World's Leading Hand Strengthener

This is a beautifully engineered product. I could sit and stare at it for hours.I've got particularly long fingers (possibly marfans syndrome) and they're just OK - they'll be perfect for the average consumer. Expensive but worth the price when you look at the quality. I had some cheap grippers previously and the handle soon began to spin and then became useless, whilst plastic ones have broken over time.I ordered two pairs separately:One was a Saturday, it dispatched on Sunday and turned up Tuesday midday - really quick over a weekend and during COVID.The other was ordered on a Wednesday and it turned up on the Saturday - again, really quick delivery.Very pleased and looking forward to improving my grip strength!

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 first, since I figured I was already close to getting 200lbs, so 140lbs should be easy...Guess again.Well, I still loved the quality of the gripper, so almost immediately ordered the Trainer, to give me a lighter weight to warm up with.Pleased that I could close that (100lbs), but decided to round things out by also ordering this “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 Guide & Trainer were both a bit squeaky initially, but that was soon remedied with some 3-in-1 oil application.We’ve also now got some really light squishers & bands for finger extensions too (all pictured).Overall, we’d definitely recommend the CoC family of grippers.

A very good, excellent gripper. Handles wider apart than a similar gripper. Need a little more starting pressure to close these. Rated 365lb and I would say that's about right but can't confirm because I am nowhere near closing these completely. A finer instrument for gripping success may never have been devised.

Really well-made grippers, and I don't really see the point about the knurling that some others have made, as it doesn't feel uncomfortable to me. I spent quite a while deciding on the level of grippers to purchase, and went for Guide as I'd been away from training for quite a while, but I found them easier than I thought, so I think I will need to step up almost immediately. If you've ever trained before I would suggest going straight to Sport or Trainer, as you probably have more residual strength than you think. That said, I can see myself steadily working through the next few levels and the grippers being tough enough to take whatever I can throw at them. A quality product.

Hi going by the comment by ge not being rude please dont buy or use these for a laughthese are a serious piece of equipment and useing them for a lagh could result in serious injury maybe for life so please use this item with respect and not not a laughyes they are hard to close but like anything it takes time to develop the strength to close these and use them as you would any serious piece of equipment these are for serious strength training not a laug it took me 6 moths to fully close them the reping quaility not quainty is the key but not to use them for a laugh think about it one thing dont over do it and yes they make a noise as in comments on no2 crusher why complain they are tough but dont try to run before you can walk some complaints are ridiclous as some comments ie they make the person ancious come folks as they say just do it why complain thankyou

I wasn't sure whether to get the starting set but even the lowest power version gives a reasonable workout. The higher power versions must be tough - looking forward to the challenge.

Other reviews have stated that the 60lbs. gripper may be too light for a beginner.I do not have a super strong grip(much to my chagrin) but I believe I could close a stronger gripper for one rep.Unfortunately I don't know how much higher I should go. I've ordered a 100lbs. gripper - when it arrives I will post a review on it.As has been mentioned before there is a bit of a squeak.When I perform the exercise my thumbs don't really seem to come into play, my little fingers also seem to be considerably weaker than the other fingers.

Very well made product. Even the easiest rated one is quite challenging. Quick dispatch.

top quality and standard gripper hard to squeeze as expected 👍

Nothing to dislike. Very well made

It was awesome 😎

ピクリとは動きますが…それ以上握れません。大きな目標ができたと、喜んでおります！グリップが金属なので…何回も握ると痛くなりますが、冷たくて気持ちいいです。

Very durable and strong will make your hands the same thing
