Iron Gloves Sport Gravity Gripp Hand Strengthener - Improve Grip Strength for Rock Climbing, Weightlifting & Rehabilitation - Premium Hand Exercise Equipment for Athletes & Physical Therapy

I ordered this because a friend had one and I thought it would be useful. I received the item today and it is definitely not the same as the one my friend had ( even though I ordered the same exact one) this one feels like a cheap knockoff it also doesn’t have any brand label on it . The one I have will work fine but I think I was shipped a sub-par itemOrdered three (3) one-pound "Original" Gravity Gripp balls (an excellent product) to replace same items which had worn out due to extensive use. Each ball came in a separate delivery on different days. First delivery contained a single 1-ib Gravity Gripp ball (exactly what I had ordered). Subsequent two deliveries contained a single blue "Gripp II" squeeze ball, which is not nearly as heavy nor as grip-resistant as the 1-lb Gravity Gripp ball. They'll do for backup, but I'm VERY disappointed as this is the first Amazon-marketed product which I've purchased that isn't what it's advertised to be...recommend avoiding this specific vendor and finding another sourceOrdered a black 1lb stress ball, got a black generally spherical shape rubber object pack so tightly with steel that it has little or no flexibility. Now three days later have a semi-black, mostly green, generally spherical shaped object that I feel will soon burst.I love these things. I had the exact same one for years until it finally wore a hole in it so I'm replacing it. It weighs a pound and is pretty tough to squeeze, thus the workout, and it works well as a stress ball too. Just know that although there are a bunch of layers of stretch material on the outside, it can still wear down or get punctured and eventually let all the inner stuff out. They make a 2 lb version too which I haven't tried but this one is pretty tough to squeeze and carry around itself. Highly recommended.Awesome love em easy to grab'n'go toss em around 4 miles w/30# great 4 squeezing out the pain just 1 thing cover wears out too soonThis was the best exercise/stress relief ball i have ever used. I broke my wrist several years ago and have a bad habit of cracking my knuckles. I used the ball to help prevent carpal tunnel and cracking my knuckles at the office. The only problem was i had worn through the elastic casing in about a month.Love these ... doesn't get 5 stars because they don't last that long, but while they are still intact, it's a great product.Do NOT purchase this item!! 1st. The way the company packages the ball is horrible. When you try and take off the packaging, it automatically tears the ball’s first rubber coating. 2nd. I had the ball literally two days before it popped open causing a huge mess everywhere. Complete waste of money!
