It yellows the glue. It runs a large amount. Compared to a cheap one from Praktiker, the one from Praktiker was much better

It does exactly what it describes. It looks high quality. It doesn't leak, you can pour the desired amount. It also comes with spare parts for multiple uses.

The best thing that has ever passed through my hands, I have it for 5 days and it doesn't understand anything, it's perfect, it works professionally. I have thrown away 5 cheaper ones so far, not like this one because they become dogs. It heats up instantly in 3 minutes, it's ready, it doesn't leak or anything, tireless. Get it with closed eyes

It is possible that I came across a defective one, but the result is the same. 1. The tip leaks. 2. It boils the glue without melting it, and it comes out in bubbles and in a very liquid form, almost like water (tested with glue that came with it and another one I bought). 3. It does not have a continuous and progressive flow depending on the pressure of the trigger. It seems very high quality otherwise and feels very good in the hand.
