Travelwize, do not buy if you need to wheel your cases around

Do Not Buy. Quality is poor and customer service worse. Bought 4 new cases, on our first air trip using 2 of them, one of the wheels broke. Sent email and I asked where I can buy spares, it was read but no reply. No point in buying if you cannot fix them, also could not trust using them on an overseas trip, unless you are prepared to lug your baggage aroundwithout wheels.
