I've used them a few times in the past. I found them to be extremely fussy to get right. Not enough heat and you don't get a good connection, too much heat and every thing overmelts and burns. It was a very fine line between the two. As others have said, as few connections as I do these days, it's quicker and easier for me to do it the old fashioned way with strippers and crimpers and then shrink tube.
