The first small negative point of an unpleasantly noticeable and so I can not explain to me why you take to sew a gray belt in an orange housing a light blue thread ?! This has very cheap. Luckily you can see the place rarely, namely when the belt is fully rolled out.
The second point: the belt is not completely closed in the Exterior, but the role is on two sides out there (because I find the "old" solution, where the role was complete in housing, better).
And the third point of criticism (of perhaps the second is connected): Sometimes the belt increased when rolling back, especially if slightly damp. One can then see that the belt is not completely clean wound on the role and eventually blocked themselves. With the old Flexi I had never the problem. I'll watch more, and the error should occur often times, that would be a reason for complaint for me.
Otherwise, the line is of good use when the dog in its movement does not want too much to limit and at the same time want to have under control him.
