I had high hopes for these but I find them challenging to use on grass (difficult to stake so they’re level and vertically straight). But worse, within a few uses one of the poles in its base fell off the mounting screw. The hole in the base is too large for the screw so I’m unable to reattach. I didn’t return because I thought it must be an easy fix; it might be, in fact, but I haven’t yet determined what I need to purchase in order to make it work. And, really, I shouldn’t have to. It should have lasted far longer; however, to be fair, the other five poles are fine. But since the issue isn’t with an end pole; it makes it kind of a useless set. I’d be reasonably happy without the attachment issue. It’s an inexpensive set of training poles, and I didn’t expect perfection when I purchased!
