As an amateur, I can say that it is excellent; I never encountered any leakage or any problem. I have used it for various repairs and maintenance, such as on the solar water heater pipes, faucets, and maintenance in the boiler room of the radiator in the closed circuit. I also used it on a connection in the oil supply pipe of the burner from the tank, which is easily accessible for inspection and repair if needed, and I did not encounter any problem.

I have also happened to use it for other purposes, and in an emergency, it got me out of a difficult situation, such as when I was changing the oil in the engine and lost the sealing washer of the oil pan plug. It was Sunday, everything was closed, so I used the thread for sealing, and it held perfectly until the next oil change months later without any leakage…

Even on screws that do not need sealing but need to be tightened more firmly without bottoming out…

On the first use with the bathroom faucet, it didn't work well for me in combination with hemp fiber. The faucet had a leak. As soon as I worked with the classic 12mm Teflon tape in combination with hemp, the result was flawless. Maybe I should have used the Teflon thread alone, or perhaps it will work better in other applications, so I will return with an update

As an amateur, I consider it a very good product. Always compared to hemp, because Teflon tape is not suitable for sealing with requirements, especially for metal components. The tape is essentially not for sealing, but only for lubricating the threads so that they tighten and loosen easily. When you tighten a metal thread, the tape dissolves. However, there are plumbers who use Teflon tape for everything, be careful!
Hemp:
1) requires the right technique, something that even some professionals do not possess, especially when they are in a hurry, which they always are. There may still be plumbers who just slap it on and use putty or paint, which is completely wrong.
2) smells bad
3) almost always has a bad aesthetic result on visible pipes in the house.

For me, this product is really good, the only issue is that the plastic valve leaked on the galvanized pipe. On the back, it states how many rotations it needs depending on the diameter of the pipe

Excellent product, fast sealing, secure, does not leak, easy to use, immediately releases water pressure, with instructions for gas and drinking water, I have used it many times on all types of threads, I apply as indicated on the label and two extra turns

It is the intermediate in liquid Teflon and Teflon, when you need to place, for example, a switch and give water immediately, it is ideal.

My plumber, whom I consider excellent at his job, is absolutely in favor of cannabis. Compared to Teflon, he prefers this specific product, and because I trust him blindly in everything he says, I followed his advice and bought it. My first test was successful. It didn't leak a single drop, so just the fact that he recommended it is enough for me to give it 5 stars.

Very nice product, with proper use it has never leaked on me. Many people, out of habit from using hemp, apply it like hemp (which is wrong for the thread) and leaks are created. If you follow the correct rotations as well as the cross wrapping outside the joint, you will not see any leaks.

I am an amateur, I don't think it has anything particularly different from the others. I did my job.

Simply amazing, no more sticky Teflon! And yes, with the rotations mentioned in the instructions, it seals. The "trick" is the notches in the thread as stated, of course, in the user manual.

A little thread is enough for a good waterproofing. This specific product is affordable for this specific reason

Thanks to the multilayer pipes (pex-al-pex) and the sealing thread, I became...a plumber!
I changed all the pipes in my house with minimal cost (and excellent results) by myself!
5 stars are not enough!
