Anyone used Obi Baby carrier belt?

A friend has just sent me a link to their you-tube video, & I have to admit it does look good.

DS is 2 & 7mths, about 14kg. He's pretty good at walking, but gets tired on long walks, and this belt looks really great & very portable, but the straps look like they might dig in to the legs & the bum is unsupported?

Has anyone used one before? Is it worth ordering one?

TIA

I've not used one but It looks really uncomfortable to me. What about a Boba Air? Very lightweight. I've not used one but I would like one but I think DS is getting to heavy so I have a Podagi instead.
