I remove one star for the brake.
The old one was easier for me.
I have been using the 10 meter for almost 30 years

At 40 kilos, which is the weight of the dog, it brakes and holds just fine.
The 10-meter leash is perfect for large spaces to let it "free." It's a bit heavy and the handle is a bit awkward, but you get used to it.
The only bad thing is that in the company's basic series there was a recess to fit a flashlight and an accessory for bags, which this one doesn't have, and I found that convenient

fantastic guide. of course, it is not intended for dogs with sharp teeth that tend to bite their leash because it cuts easily.

Excellent in every way. In a very lively 32-kilogram drachthaar, it responds wonderfully. Quick recovery, durable, with a very good grip.

I have the flexi giant 8m for over 50 kg. My dog is 23 kg but during walks, she pulled a lot; the 23 kg felt like 100 and I couldn't hold her back, she would run suddenly and generally, the walk was often a nightmare. It seemed like she was taking me for a walk and not the other way around! That's why I was looking for a leash that could withstand very difficult situations and allow her to move a little away from me without me running behind her pulling. Now the walk is relaxed, she magically stopped pulling, and we both enjoy it!!!!! As for its durability, it seems very stable with good quality. Its weight is not annoying at all; on the contrary, I feel it and hold it better. For those of you considering it, get it with your eyes closed. There is no better!!!!!

I have been using it for about 3 months. On the positive side, the leash retracts quickly and does not hang if the dog has moved away and starts running towards you. So far, the mechanism has no issues and seems durable. On the negative side, it is bulky, but this is justified due to the large leash.

Just what I need for a very active Akita over 3 years old who wants to be at a considerable distance from her "dad" during walks, but at the same time needs to be able to be stopped instantly when she bolts despite her weight and momentum. It lasted 2 years with continuous use, still very sturdy even where I thought it wouldn't hold up, with many kilometers being dragged freely on rough terrain, and 2 summers at the beach. Now the mechanism that retracts it is broken, so I'm going back for a new one but exactly the same

There is no better option for me as an owner who provides space for the dog but also for my dog who moves more freely... sturdy quality construction with a safety stop.... very satisfied and considering the price, it has broken 3 cheap ones, it will come cheaper in the long run

The best purchase I have made. Now walks have a different meaning. I had a big issue with the pulling my dog did with regular leashes, but with this one, he will go 2-3 meters, sniff around, and come back on his own. The dog is free to move without any pulling. You can stop him at any time by pressing a button. At the beginning, I would suggest trying it in a safe outdoor area to see how it works and how your dog reacts. As for the construction, I haven't found any flaws or vulnerable points so far. It is a sturdy construction with good materials and a comfortable handle. The package also includes a strap to secure it, for example, to a pipe. The only negative thing I can find is its weight, but that is due to its good construction and the fact that it is for dogs up to 50kg. It will probably be lighter for smaller dogs. However, its weight is not discouraging for long walks. I highly recommend it without a second thought. Enjoy your walks.
