The only issue I've seen is the design for the koozie. It is a velcro overlap that, when installed on the coil pipe, creates a section that is deeper that the feet of the pipe. This essentially makes your pipe a glass rolling pin.

I cut off the excess of the koozie and sewed it back together by hand. The material is flexible enough to slide back on the pipe, over the fill cap, and remain snugly in place, letting the feet of the pipe keep it stable.

Great products, but clearly the koozie designer never tested this out in the field.
