As soon as I turned water back on to the house, the ex tubing shot out of the push fitting, spraying across my kitchen and pouring water into my basement.  After I had shut water off, capped the open tube, and cleaned up, I tried a new piece of tubing in the connector and found it pulled out with maybe 4 pounds of force.

When I called Sharkbite's technical support, the only assistance offered was that they've not heard of this or any similar problems before, so they recommended buying a new one and trying again.  Thankfully Amazon's return policy and customer service make up for Sharkbite's lack of concern for my experience, and this connection was accessible so although cleanup was painful, drywall repair isn't necessary.

I've attached a video showing how easily the tubing is removed (this is after 3 or 4 insertions). I don't believe this is typical of Sharkbite, but if not, you'd think they might be more concerned about troubleshooting...
