Query: Gotta get these!

This product is amazing. These work perfectly with p90x as you have to change weights constantly. They also take up very little space. They do everything they say that they will do!Thus far I've had zero problems out of them and I use them 5-6x's per week and I've owned them since July. The ONLY THING I SUGGEST is.......bat tape! The handles are very tough and not user friendly. I bought some easton bat tape and wrapped the handles and now it's perfect.Another FYI...these are not as durable as traditional weights. You can't throw them down like like you would other weights. They are not designed for that. They are designed to be used and then put back into their base....Well worth their money.
