Cardboard canvas

[Pork]

Sorry if this has been discussed before, but the search button is still down.

Saw an advert in a photo mag for www.jetmaster-systems.com and seems an interesting alternative to an expensive canvas? Anyone have any experience with them before? Instruction Video

Some of the canvas that you can get professionally supplied come with adjusters to tighten it as it stretches slightly over time, I imagine that a cardboard framework would not last too long, especially if you have any damp in your home, not seen them so this is just a guess

looks like an interesting idea but I can't help thinking it also looks a bit "cheap".
