After 7 years with our Intex it finally started to give out, the problem was the legs and beams started to rust and luckily we were able to finish out the year with it. We will be ordering another one soon but have a question, I saw an add for a replacement joint assembly that connects the leg and the cross beams together that was made of plastic, has anyone here used them? My only issue with them is they are pricey at about $33 a piece.
