Who uses a Flexi, it should at least let his dog bestow a certain level of education, since the 8 meter range ranging from the dog to give so much momentum that it drags the master on the fly, this then leads the dog handler to the well-known three-point landing - head - shoulder - walk! Therefore, you should before embarking on the greatest bustle for a quiet place to practice / try looking to master and dog on the Flexi get used. If it is done properly setting the dog very quickly when the line is at an end, and how great is its radius with the new Flexi.
To be able to better estimate when the line actually reached the end, I did this 2 meter and 1 meter before the end marked in color on the flat band and so I can now then prepare in time to stop. Especially on large forest trails and fields you can misjudge very quickly, how long (short) are actually 8 meters and is then more surprised when the attack comes. Depending on the dog it makes sense to either work with a Retriever collar or in dogs that are not quite so rough can also wonderfully K9 harness is used which has the advantage that is out of the dog on the padded back.
This makes the leash roll up again and again, it remains opposed to a towline always clean and you also stumble not about that.
The retractable cord performs reliably his service - a tangle of flat canvas does not exist, and in contrast to the flat round rope leash has the advantage that it does not contract / jammed when the dog jerks or pulls on the role permanently.
The weight is just not to be underestimated on longer walks 2h +, so I hang me these Flexi with a 2nd line drawn through the handle on the shoulder, especially if you are traveling with 2 dogs to offers this to at least one to have a free hand.
From the stability linen and housing is quite adequately dimensioned so that they safely withstand even a rough use and is still capable of pulling behind him the master. The stopper keeps as long as you manage to keep the handle - as the handle is softly padded, easy handling is always present.
Overall, a strong buy recommendation.
