I've been using it for a few years, and now just put one on my daughter's bike. She, a triathlete first and cyclist second, and I, just a cyclist, are using it very differently.
BTW, I've recently installed a Stages (DA9000) which replaced the PowerTap SL+ hub based power meter. During the transition, I had them both on it and I paired the Stages to my iPhone (using BT) and check the numbers between the two. They were very close with Stages about 2% lower on most rides and just a tad higher on climbing. All in all, I would say they are close enough to be the same.
My daughter has the PT C1 chainrings on a Rotor 3D. It's nice because it's double sided. Installation was very easy but you do need to take out the crankset out of the bottom bracket to install. I also did a check between the PT C1 and PT SL+ wheel. The numbers came out almost to be identical; it's probably not surprising given they using the same software from PT.
