Unfortunately, a mixed review. I ordered a pair of rails for my son's birthday, ones he had selected from the webpage... the package arrived fine but there was only one rail, not the expected pair. I contacted Slam City the next morning, getting a reply the following morning to apologise and to promise to send out a new pair. This new pair did indeed arrive the next day, but unfortunately it was a different brand of rails from the one we had ordered... my son had specifically picked the ones he wanted, remember. So after two attempts, we now have one rail of the right brand and two of a non-preferred brand. Sure, they work... but ... Oh well.
