SPRI Thumblock Wrist Weight Set

Perfectas y muy resistentes

Take a look at the 1-2 star reviews, almost every one of them talks about this product leaking - coincidence? During the very first use I noticed little grains appearing on the floor when I used these but I could not detect any holes so shrugged it off as 'breaking them in'. Less than 2 weeks later and maybe 10 sessions of use they are both leaking badly. The issue I feel is that the iron sand is basically little miss-shapes of iron, some like little ball bearings but others are like little shavings and they can be fairly sharp. The material holding the sand is stretchy and not strong enough, and so the sand just ends up bullying its way through. Mine are leaking from multiple points on each weight and there is iron sand everywhere. Not impressed. If I persevered with these they would be empty before long and not weigh anything. The fault with these is too severe to be a one off, this isn't a missed stitch, its just badly designed. If the filling was of a higher quality, maybe just larger spherical balls and no sharp bits then maybe these could work.

Update 08/14/21 I bought these in March and for a few months they were a great addition until the little black metal sand started to leak from them. I tried to work around it but after a while it became too distracting. So I stopped using them. Too bad because they are nice items. I wish the fabric was a bit more sturdy so the sand leakage wouldn’t happen I love this thing. I use it when I’m working out in VR. It helps in toning and building muscles. I’ve had it for a two months and no complaints on my part.

So cheap but great quality and nice in the all black.

very light. useless for me. I'll give it to my 12 year old son.
