I've used the same type fittings by a different manufacturer but only on inside pipes. I haven't had any issues with them leaking but since they're new to me, I haven't built a lot of trust in them. The shark bite site says they are fully approved, even for use on buried piping... They do make things a hell of a lot easier/quicker (and possibly safer), than sweating/soldering. But I do trust a properly done solder joint 100%.
