3 way coupling lead

Those of us who regularly walk 2 dogs at once will be familiar with the 2-way coupling lead, but walking 3 dogs can be a bit of a challenge.  I recently found this whilst browsing the internet, and thought it was a good idea –  not so good if the dogs decide to play “knit one, purl one” though!  If you have used this type of lead, do let me know how you got on.
