Have used the cutter (v. good) and flarer (fine). This is the same as similar products on other online sites, including those starting with an "e" and involving auctions but better priced. I got from a local warehouse so shipping was fast and along with the fact that it is of seemingly very good build quality with good machining/threads, is recommended if you like to work with copper (like me, a non plumber but use copper to design and heatsink LED lighting pieces).
