Bought this for Father's Day to spend time with my two teenage sons. The last time I used something like this was over 30 years ago and it's a lot more advanced. First, the temperature controller is very convenient and very easy to adjust. Second, there are so many different tips to choose from that I wanted to try them all! A few negative things that come to mind: 1. There is no easy way to organize tooltips once opened. 2. It's not very comfortable to hold, not sure if it's possible, but I'd like to hold it like a pencil, closer to the tip. All in all a great set for beginners.
