Put the heat gun on your work surface facing up (the flat back allows it to be used hands-free), and keep the wire moving / rolling to avoid burning and bubbling - works like a charm. YMMV.
I don't do a ton of soldering, but these things are a lifesaver when I do!

You can use torch/lighter but you run the risk of burning them. Much easier to use heat gun. To melt the solder ring inside, you need to keep a steady temperature on it which can be very difficult with a flame
I have a heat gun from harbor freight which has low and high. The low setting was too weak to melt the solder. The high setting melted the solder, but the plastic develops holes very early. The plastic is way too thin and fragile.
Bought this same item on the listing, had the exact same experience. I can't recommend these to anyone, horrible material.

It's not as easy as the advertisement shows. To melt the solder, you need to put heat gun on high and keep moving the heat gun around. The higher the gauge the harder it is to melt the solder. Remember, to properly tin/solder, you MUST get the copper underneath the ring to the same temp (tricky to do underneath an insulating tube). It takes patience. These connectors are the best when you want to keep the final diameter of the wire small as possible and don't want a huge fat bump on a cable.
