Has anyone tried out these mantra 3 in 1 foils yet?

Are they released yet? Looks nice though.

I fancy trying one of these personally:



As a travel foil, being able to strap it onto the bottom of a twin tip sounds good - plus being able to ride it as a proper foil the rest of the time. I suspect that as with most 'all-in-one' products, it may just be disappointing at everything.
