weighs my "medium-sized" dog of about 20 kilos, the leash now been around for a while, it makes use of the haptics her a good impression, the "on / Ausrastfunktion" goes smoothly so far. Wear or malfunction, nasty ridges or workmanship I could find none. Stink does not (eg by plastic, like many others).
Five stars I forgive because the price / performance really fits here, if you're comparing with cheap dog leashes from the supermarket better processing (at the Flexi) and the roll-up worked previously with no problems whatsoever or "between flips".
Could improve one only the weight (to make something easier) and one probably. make something small, but at the price that's not the problem.
Dog and owner can assign unscrupulously 5 star here.
