Ok, it arrived half an hour ago and I'm very pleased with it (for £30!!!). It's very snazzy (well, for Cornwall)!! DD's not so impressed but she's in a snotty mood anyway.
It feels quite heavy on the shoulders but I may be doing it wrong!!! But I'd be happy carrying it even if it will always be mostly on the shoulders. There's 2 straps across your front - one above your tits and one round your waist so that makes it feel really secure. The waist and shoulder straps are really nicely padded and there's 2 pockets on the waist, handy for purse, keys, phone, dirt etc. It's really easy to use and get to grips with (got to be if I can use it!) and the bag that fits onto the back is huge, so I can easily put all dd's stuff in for going out. At a push, I reckon I could fit everything I need in for a weekend away! (Not that I'm going to get a weekend away mind!)
Natch, it doesn't seem quite in the league of the bushbaby one but its not quite in the same price league either. My only minor worry is that it won't quite make the upper age limit in comfort but I haven't tried so I don't know for sure. And even if it's only useful for a year or so, that's fine with me.
All in all, I'm really pleased with it - arrived really quickly, does exactly what it says on the tin. Really easy to use and really comfy. Bd - I even like the colour too!!
Hercules - I'd definitely get one if I were you!
