What you need to know:
Like just about everything from XTraining, a great quality piece of equipment that can take a beating and get through done great workouts.
Great design, works as well, if not better than any of the other products out there. Great job x training
Purchased 10 of these to use during strength and condition sessions for JROTC cadets and for our Raider competitions. I left the skids on a few for use on asphalt and took them off the rest for use on our grass field. We have used them empty and up to 290# of weight with no variance in performance. We push, pull and have tandem teams push/pull simultaneously depending on what I can dream up. These sleds are very heartily built and have withstood everything a bunch of teens can put them through. Definitely recommend these for any type of sled workouts you come up with.
Easy to assemble, but had to remove skid plates to slide on carpet. Squared off front edges would catch and dig in.
Bad *** equipment! The best!
