If you were a plumber, I bet you would cut off the homeowner **** and put on real fittings
I'm not a real plumber, but I do play one in a brewery.
The Sharkbites have their place--a place where you know you'll be removing the line on a fairly regular basis. For most, it's barbs and Oetiker clamps. I've had too many Sharkbites fail and leak even in a perfectly static (not that there actually is such a thing in plumbing) situations. I use a lot of John Guest fittings for gas/air lines, which are basically what the Sharkbites are copies of. The JG fittings seems to be better quality, but will also fail eventually.
PEX barbs and Oetikers are cheaper, too. The tool for the Oetikers (get one, it does make a difference) is kind of expensive--once. Then it's about a four-to-one price advantage over the Sharkbite removeables.
I hate those little orange thingies. I usually use either Crescent or OE wrenches, but those pliers-type look intriguing. There are times you just can't get a good enough grip for the slip-on tricks--or there's not enough room to use all three hands.
