Hand Gripper Strengthener Set 50LB-300LB, Grip Strength Trainer (1/2/4/6 Pack) Forearm Strengthener for Muscle Building, Hand Sensitivity Training, Hand Rehabilitation Exercising

Pros: I'm very impressed with the quality. They are light weight construction and yet are solid as rocks. The difference between each weight level can be felt. I feel my grip becoming stronger than before. These are a bargain buy. What to know: The texture on the handles provides great grip but can dig into softer hands. It comes with sleeves to put on them, but I just use workout gloves. Sleeves add bulk to them.

These are basically indestructible....so that's enough for me, not sure why people are paying like $75-200 for plastic digital ones that will more then likely shatter into pieces after the first couple of months. These should be a great set for anyone getting started, some people feel like 50 pound jumps are too much but honestly I feel it's adequate. The 50's were too weak for me, I started off on the 100 instead but It hasn't been a week and I've already decided to move up to the 150. I will say though that I can see myself being on that one for a bit before I feel comfortable moving up to the 200. I don't need a display to tell me how much pressure pushing because it says it on the bottom. The little foam pads will likely wear out over time but are really cheap and can be easily found on here. They will likely not be comfortable without the cover's. I can imagine some really huge guys feeling like the 200 pound ones aren't quite enough but for most people I would imagine it will be. I'm working my way up to them, but even when you do, if you feel like your able to do plenty of reps, just start holding them in longer, or try to find some stronger ones.

These are great devices to improve grip strength. E21ach one feels sturdy and well made. I've only been using them for a short time, but I can tell they will last indefinitely. The handles are made of knurled aluminum and the spring is steel. They come with rubber cushions, but I don't mind callouses. The price was reasonable and they arrived in a short time.

The plastic type of these i got broke in less than 2 weeks. These are still going strong after several months

The strengths are perfect for everyone!! My wife uses the 50lb and Im working my way up to the 300lb.
