So I ordered one of these hoping to add some dart storage to my half-dart firing Knockout but I have not had any luck with it. The first issue I had with this product was not being able to fit the nut into the body of the cover which meant I could not screw the 2 body pieces together. I contacted customer service and quickly received a replacement. I was expecting the installation process to work this time but sadly that wasn't the case. I was able to fit the nuts into the cover body now but then I ran into a different problem: the head of the screw that holds the body pieces together would not fit in the hole. I took out the original body piece that I had to see if it had the same issue and while I was able to force it down the hole, I was unable to get it to turn which meant I could not attach the 2 body pieces together. After that I decided to throw in the towel and give up on it.
