Has anyone used Kaiser Thermo Footmuff on Maclaren Techno XT?

If you have, would be v grateful if you could let me know whether it fits. says is universal but last universal foot muff we bought was thoroughly annoying as kept slipping down. Thank you in advance.

I don't have one on a Mclaren but I do use mine in my P&T and it's fine. It's not so fantastic in my 'O'Baby travel buggy (slips down) but the straps are very narrow on that and there's not much to grip on to! I'm not sure if that's remotely helpful. You're welcome to come and have a look if it would help!

How kind, thank you! Shall shout if can't find one in shops to try.
