My family and I bought two of these cases as we were going on holiday about a year ago. We bought a small one for my sister and then a big one for the rest of the family (can't remember the actual inch measurements). These cases were fairly cheap and you can now get a set of 4 for £50. However, they don't look massively cheap.

The quality of them isn't too bad, however, the zip does tend to stick on one of them. This could just be a fault with one case because the zip is fine on the other one. Although the zips on both cases aren't the smoothest that I've ever seen.

The cases are fairly lightweight and they have a strap inside so that you can attach it over your clothes. This means that if your case gets thrown about at the airport or in the car your clothes will still stay nice and neat. The wheels are fairly good and the handle is a good length for people that are slightly taller. These cases also come with a lock which is good if you don't have one spare. They are quite small locks though so they probably could be easily broken.
