Positive: good workmanship and excellent operability, since one has everything you need: plenty of space, bag can be closed, strap, solid aluminum frame and arm, the one easily or can be extended and we can all trolley (with some effort) be folded completely well, so that it is flat and fits in anywhere. So value for money top!
We have but the roles disturbed too much, so I have a chassis with inline wheels off tinkered and now the trolley rolls even when fully loaded with tolerable inline volume.
