It ends up being a single-use glue: after the first use and after the mixing tube was removed, cleaned, and covered with the provided cap, it was impossible to reuse it since the component outlets dried up. Very expensive for just one use.

I have bought it two or three times from a large toy store... Some things it sticks well... Especially if you heat the bonding point a little... But not everything... It makes a strong bond but it doesn't seem to hold over time... It cleans easily from the hands... The first time I couldn't open the two holes well and had to cut a little with a knife... The next time I opened them better... After use, it closes with the black cap... On the next use, the holes need to be opened with a toothpick... I haven't needed the tip it has so far... For some things, I use it together with instant glue for better results... Generally, I always have a tube of this at home... But for more successful things, look towards bison... For more serious jobs, that is.... That's it... Recently, the gear lever in my car came off, I used this one and a little from bison for metals and it became solid... It bonded perfectly...

I don't know if I got a defective tube, but when I removed the top part to reveal the 2 holes in the tubes, there was only one. So I started cutting deeper with a knife to uncover the second one, thinking that maybe I had opened it incorrectly. Not even close. The result was that I had to use a screwdriver to open it, and in the end, I threw it away as it was.
Another mistake of this particular product is the nozzle it comes with. If it worked properly, the nozzle along with the remaining material inside would be thrown away, resulting in wasted material. If you only plan to use it once, then you might be fine, but if you surpass the first issue I mentioned, then I recommend choosing something with a different design or without a nozzle, as you will be wasting material.
What can I say, it's the first time I have to search for a video on how to open and use glue. Unacceptable.
I suggest choosing something with a cap or without a nozzle, as you will be throwing away material.
