First of all, I noticed that to carry it wasn't a simple task. In fact, it was rather a task because it's not well balanced; in other words, the weight is not balanced evenly when using the handle to carry it along. Second of all, after a couple of weeks of using it, one of the casters (wheels) snapped which led me to conclude, on inspection, that the material (plastic) used to support the caster is not strong enough to carry the weight of an amp head. Luckily, the Thomann personnel were able to replace the Transporter fairly quickly. So far I haven't had any further problems since the replacement. To summarise: a very good idea which could have been put into practice a lot better. After all, I did not carry the Transporter on hard, cobbled roads. It needs improvements.
