The heating time is about 70-90 seconds, it has a good stop and does not heat the silicone on the nozzle if you don't press the trigger, resulting in needing a lot of force on the trigger to start. Very good choice.

Average gun. Its positives are that it is battery-operated, so you have freedom of movement, and that the fast charger actually charges the 2nd battery in 1 hour. Its negatives are that the 60 seconds they mention in the specifications actually take around 9-10 minutes for it to be able to be used, and after it heats up, if you press it continuously 3-4 times, it takes about half a minute to be able to shoot again. It also runs. If I didn't need it for stairs so that I wouldn't have to go up and down, I wouldn't buy it
