This is a nice tool. Heavy weight and it really doesn't seem like it will break with hard use. It made a very nice bubble flare after 6 tries. However, it was really 2 tries, because for the first 4 tries I was following the directions. That was a mistake, because (although they say bubble flare) they are directions for a double flare tool. Throw the directions away and watch a YouTube video. By the way, both the directions on the cover and inside the box are the wrong ones. So, I recommend buying the tool. Just ignore the directions. Again, nice tool!
