Just rating as a sliding aid, works great! Fast!

The fit is the pull on sleeve things is terrible. It is huge! Luckily I sew, and was able to take it in several inches. Took two attempts to take in enough.

Can one just buy the disk????
The disk attaches by Velcro, and i prefer it on my volleyball knee pads instead of the pull on sleeve things provided.

Amending my review of February 3, I found that I may have been attaching the knee slider a little too low on my knee. I now find that little adjustment, if any, is needed when getting into the hack. The more I use this device, the more comfortable I am becoming with it. Thanks to Darcy for reaching out to me and expressing concern for any dissatisfaction I had and Dakota's willingness to make things right. They are good people to deal with.

This has helped with my line and stability in sliding. It has also helped with giving me a more consistent delivery with my bad knee.

I've been curling almost 50 years and find I need a little help with stability. When this knee slider is in place, it can work properly. But the elasticized velcro straps don't stay tight around the leg. I have to constantly readjust it before stepping into the hack. At this price point I would not buy another unless the straps were reconfigured to fit more securely.

I'm 63 & took up curling last year in a novice league. I'm a bit chunky at 235lbs and don't fold up like a pocket knife anymore. I drag my right knee to remain stable, and this shortens my slide considerably. Using this I slide out 2-3x further so it is a big help in delivery and accuracy. Got a little bit pricey delivering to BC in Canada but justifying it to myself as equipment needed to improve my game. If you find you drag your trailing knee and it limits your slide this is for you!! :^)
