I love this bag!
I've had it for 18 months now, using it nearly every day, and it is still in as good a condition as it was when I got it. It's definitely very well made.
Although the pram clips are only velcro they are very strong. I haven't used them much but, when I have, they have held the bag up brilliantly
The bag itself really does store a lot. As an example, at the moment it tends to have:
Changing pod - 3 nappies, wipes, bags, small pot cream, spare dress.
Food pod - sippy cup, bib, sometimes a bowl, pots of food, cutlery
Outer pocket - make up, pen, phone, a lot of receipts!
Main section - wallet,suncream, DD's sunglasses, my sunglasses, hat, camera, notepad, bottle of calpol, small book, various bits and pieces I seem to collect and never turf out!
The strap is wide enough that it is still comfortable even when the bag is heavy (and I do seem to fill it so it is very heavy!).
My DD is now 20 months and loves to carry the food pod as her backpack (which creates even more space for me to fill in the bag!)
My only slight criticism is that the opening of the main pocket is only about 20cm wide, and the pocket is not big enough to hold A4 size things. Probably not something most people would worry about but on occasion being able to carry A4 things in it would have been useful.
Overall I would definitely recommend this bag if you want a nice leather changing bag, especially one that looks more like a handbag.
