Yup, no substitute for the good old Western Union splice and heat shrink.
I have mixed feelings about it. On one hand, personally, I think that it's a bit mickey mouse when it's just as easy to do a connection with better mechanical strength and and more surface in contact. On the other hand I'm always in favor of anything that gets someone who doesn't have much shop experience to try and do something for themselves rather than have to rely on others. So if it does that, I'm in favor of it.
