I've never used these--in fact, this is the first I've heard of 
them--but, of course, that never stopped me from having an opinion or 
two. My 'hot take' (heh):

1) there may be solder formulations that a heat gun could melt, but 
calling this 'solder' seems to be a mis-characterization: the 'fine 
print' says it's 'hot melt adhesive.' I didn't see anything about its 
conductivity, nor it's strength (though the shrink wrap part would be 
reinforcing).

2) when I was maintaining my own aircraft, I subscribed to a magazine 
called 'Light Plane Maintenance.' It didn't take any advertising, and 
never shied away from 'calling it like it is.' They did exhaustive 
research and experimentation on the benefit/risk of solder joints vs. 
crimp joints and came to the conclusion that crimping was superior to 
soldering (and easier, to boot). But, it has to be done properly; e.g.:

https://www.youtube.com/watch?v=eIfoSSmlQR8

3) I only see them as being used for splices; apparently, you still need 
to employ crimping or soldering for terminals (loop, spade, etc.). I'd 
prefer all my wiring to be consistent.

4) the advert claims they are 'waterproof;' that, I think, is a stretch. 
Most similar ads only claim 'water resistant' (for liability, I suspect; 
water will eventually get into almost everything).

5) for most solder joints you want to twist the bare ends together; that 
doesn't seem possible with these.

So, no dice for me.
