I bought this for my father in law. He's been suffering from a bad back and usually carries a heavy rucksack around with him for work. We chose this as a suitable alternative to carry his work files and laptop around with him, particularly as he uses public transport to get between appointments. It's even better than I thought it might be. The wheels glide easily and not just vertically but horizontally too. The zips are strong and open well and the interior is well padded, perfect go for carrying his laptop in the pocket. The ease of transporting it has improved his health already after 3 days use. The handle is sturdy too. It's also ideal for using as a cabin bag as it's spacious enough to fit overnight clothes in too. Really pleased with it and would happily recommend.
