I purchased SRAM XX1 Eagle Power Meter and have not had any issues with it. Other power meters I have that are left side only I frequently get random power spikes along with corresponding cadence spikes, and the solution from that vendor was to come up with their own program to try and filter out the false readings. Battery is easy and quick to change, I've had it over 6 months and only had to change it once. This is with about 8-10 hours of riding per week. If my next mountain bike needs a different power meter it will likely be a Quarq.

Great Product, works flawlessly. I have and older Legacy unit on my time trail bike and a more recent one on my road bike. They have always worked flawlessly and remain paired and well integrated with my Garmin 1000. Excellent customer service, always helpful and friendly.
