I have had a set of these for over a year and they are awesome. The way they unscrew but have a string to keep the two sides together is very convenient for travel. I got a bag to store a set of cones and these poles and am able to easily set-up a jumpers course on the fly in a parking lot or field. I also appreciate that they are rigid and don't tend to bend or sag. They are a slim diameter, smaller than 3/4 PVC, so you can't exactly use them to replace jump uprights, but they are decent jump bars, and they are small enough to stick through the tops of cones.
