I purchased the Big Boy wheel kit for a slightly used Cimex I purchased. Unfortunately when I received the item it had the axle for the smaller 15" model, whereas mine was the 19". The Excellent Supply staff was not only assisting me with great tech support to do the replacement, but that's where we realized the incorrect axle was shipped. The tech didn't say, oh, contact the office, instead he said let me take care of this immediately and we'll have a replacement shipped to asap (and I believe this was his day off - gotta love that commitment). The replacement arrived a few days later and the install went smooth. I understand when things don't always go as planned, but it's how the ES staff handled the mishap that keeps this at a 4 star rating. I could almost give it a 5 star, but honestly I know I should only use that many stars if there was no issue at all. I'm hopeful that ES staff will make some adjustment to their online ordering of this item so the person orders is sure to receive the correct kit. Also, the directions look great with pic's and all, but it seems like they could use a revision for some clarification on a couple of areas (unscrewing the rod by relieving the pressure on the rod by moving the tank slightly forward, and noting that some units will need to have the set screws removed which are holding the axle in place).
