The strap is made of Dyneema material
Dyneema is an extremely durable synthetic polyethylene material, known as the "strongest fiber in the world," which is 15 times stronger than steel

Main Features
Extreme strength: It withstands enormous tensile loads and offers top-level protection against tearing and cuts.

Lightweight: It has low density (lighter than water) and offers an unbeatable strength-to-weight ratio.

Environmental resistance: It is not affected by moisture, ultraviolet (UV) radiation, and most chemicals

I've had it for three years and it's a beast! The strap doesn't tangle and doesn't tear. A bit big in the hand, but it's very good that the rope extends 8 meters when you don't want to let the dog off the leash.

I have loved this leash. I use it daily for walks with my dog, who is a 32kg pitbull, and it is excellent!! It holds very well even during strong pulls from the dog, so don’t be afraid at all—it will make your life easier compared to 1.5-2 meter leashes, and your dog will enjoy the walk more without constantly pulling you to go where he wants. Of course, you need to be careful when letting him go 10 meters away, especially if there are cars or people around you... I mainly use it in a less populated area in nature, so I am more carefree about these things.

Excellent product. I have bought it for both of my shepherd dogs. One is 28 kg and the other is 49 kg. It has amazing grip!!! Awesome!!

I have had it for a few months. So far, no signs of wear. And I emphasize that it is handling a former stray that looks like a hunting dog, 2 years old, full of energy, 40 kilos

Flexi, words are unnecessary for these leashes, I have the 10-meter (neon color) and now this one for short walks, for me there are no better leashes, both in grip and in length and in durability, don't think about it, get it and you will remember me, especially if you have a large dog

Light and durable. I highly recommend it. I have a medium to large-sized husky and I am very satisfied with the leash.

I have been a owner of this product for 1 month and the first impressions are quite satisfactory.

User-friendly handle, temporary and permanent lock.

My dog is a mixed breed weighing about 15 kg, I just believe that the stronger always performs better!

I had my dog on a leash for almost 2.5 years and as soon as I switched to a flexi, my walks became much more enjoyable.

You just need to be very careful if you are inexperienced with its use in managing it on a busy road.

I recommend it to an owner who lives in a suburban area without much traffic. In a crowded area, just a leash, folks!!

I did not expect such a sturdy construction, strong plastic, and good quality handle. For a large dog, the 8 meters are better.

For big strong breeds, only FLEXI could I trust. Strong and reliable even in strong sudden pulls.

It has a very smooth operation and is easy to use, however my first one lasted 2-3 months before it started tearing, and the second one I got now lasted 1.5 months before it also started tearing.

Initially, I was very surprised that the first one tore so quickly and the pet shop told me it may have been a faulty one. So the second time, I got one that is supposed to withstand up to 12kg, while my dog is only 6kg and generally doesn't pull during walks, nor has it ever needed to be pulled abruptly.

If it had happened once, I would say it was a coincidence, but for it to break so quickly even with regular use is not justified.

2/5 rating, only because I may be that unlucky. Otherwise, very unreliable

I have had it for quite some time to have an opinion. I have a 30-kilogram dog that pulls when he sees cats or other dogs. It is still like new, durable, and I highly recommend it without reservation.

Amazing strap. I have it for a playful boxer and it's just what I needed! Sturdy, easy to use, and with the additional accessory for bags or treats, walks have become a breeze!

Finally a proper leash. It doesn't break for any reason, at least with my 30-pound dog who pulls a lot, chases cats, etc. There is no issue at all. The automatic brake is very helpful. On the third day of getting used to the leash, I realized how correct it is. It has taken several tumbles and it doesn't even notice

Quite sturdy, a little heavy but I imagine it is justified due to the good mechanism, nice soft mechanism without sticking. It's worth its money and more. Other leashes I had bought from a pet shop for 14 and 17 euros didn't last more than 6 months. You pay 3 euros more and you have something worthwhile.

Very sturdy and reliable construction. It was preferred in the past, and preferred again! The 8-meter leash provides comfort for the dog's walk. It's worth its money!

My dog is a mixed-breed Labrador, about 30 kilograms, and I have had the leash for about seven months. It has endured countless tumbles and pulls when my dog runs with all his strength, but it doesn't suffer any damage. Its durability has impressed me. One day, my dog caught it when I was away from home and broke the handle, but I fixed it and it is 100% functional. If it ever breaks, I will buy the same one again.

I have this specific leash for a 35-kilogram Labrador retriever for over 6 years!!! The only reason I will change it is because I want to change the color!!! It is the best there is and at a very affordable price!!! You buy it now and again after 10 years!
Even the same one that I have and I put it in the sea, diving it and soaking it in saltwater, for 5 years now, just a good rinse and it is immortal!!!

So far it is very good. The large strap helps the dog move more freely and both of us enjoy the walk more

Really wonderful, before I bought it many friends of mine told me that it breaks easily, etc. I have a 30-kilo dog that really pulls when we go for a walk. I have had several incidents where the leash fell down when the dog pulled, but nothing happens apart from some external scratches. The construction is very strong, 5 stars from me

The manufacturer has been the standard in the category for years. I had it before, in the 90s, and I can say that the build quality is even better now. I've only had it for 6 days, but its good qualities have already shown.

An additional welcome feature that didn't exist before is a thin safety strap/collar (attached to the metal hook with rings) that we put around the dog's neck to hold it if the leash breaks.

The only thing I would wish for additionally would be a hand loop before the hook, like the one Flexi provides in the Freedom series that I just saw. It is very convenient for holding the dog in a direct and secure way. Oh well. Next time, even though they don't break easily as far as I remember......

Of course, I highly recommend it and it is also very affordable.
