"Best for smaller bags"
I don't think the picture does the product any favours as I would expect the whole thing to topple over as other reviews have said. However mine is in regular use (I use it to attach my laptop case, handbag or mac, in a number of combinations) and as long as the weight ratio is right, the bag shouldn't topple. It would probably help if the case has four wheels. All I know is that I am often asked where I bought it - until I came across it on the website, I had forgotten it was at Lakeland!
