I use and love them. angled grips,easy length adjustment,spring loaded,concave carbide tips. two is much better than one. I find I go faster-esp on rough ground ,feel like I'm using less energy(99.9% sure this is in my head) and it takes a lot of stress of my lower body. I have bad knees(thanks D.O.C.) and it helps a lot with them but the man thing is my f*#ked ankle (thanks sports) gets hurt a lot less.the last point is the main reason I use them as have had to sit tight for a day or two a few times before I started using them and never since.
