Hooptech Cap Frame

I am looking for feedback on the hooptech cap frame. I have a SWF 1501C and thinking about purchasing the cap frame from Hooptech - it looks like it makes hooping hats much easier. Do you like or dislike and why? Does anyone have one they want to sell? Also looking for the cap side & back frames for the Hooptech slimline 1 clamping system.
