I bought my first SEEED Mini soldering iron early in 2016. I was skeptical because I already have a nice Weller soldering station with different tips. It's robust, sturdy and gets the job done. But there was an instance where I needed to solder some leads in my car and working with the Weller made it challenging. It's big. Sure, I have had some basic soldering irons, but they all stopped working, so I no longer had a compact one.
Since I acquired the SEEED, I've been using it exclusively for all jobs. I now actually regret having the Weller because it may not get used again. I'm so happy with the SEEED, that I got a second one from a second drop in 2016 for a friend. When I joined the drops, I chose to get the additional tips and I have now used 3 out of the 4 so far. Love this tool!
