It doesn't heat up as fast as they suggest. However, it is so much more powerful than my 40 year old 15 watt unit, I don't care it I have to wait a little. At least it really works.

this is a great soldering gun only takes 30 second to a minute to heat up and u can use it for hours without it burning up on you stars across the board

Best soldering iron ive used or have owned, buy this product and u wont have any problems soldering small wires together!

I bought this to help me replace the factory wiring with 16 gauge Kicker wire, now this was my first time soldering, after reading articles and watching how to videos on YouTube it went pretty smoothly,may not have been the best looking solder job but I got it done, my only complaint is that I wish the function of the Yellow button would be clearly labeled, I couldn't tell if I had to hold it down or click on to cycle through the heat levels, other than that no complaints, great for starters like me.
