So I want to get a Footmuff for my Bugaboo Bee Plus but I'm confused about a few things?? Firstly...I have a Quinny Buzz footmuff...would that fit (thereby saving me some cash!) Secondly...is the Bugaboo footmuff worth the £90 price tag? Thirdly...how the heck do you fit the footmuff on there - I've seen people talking about the white clips at the back, but when I've had a look at them, they don't look as though they're budging!! Thx for any help.
