In 2005 PowerTap introduced the world’s first-ever wireless powermeter – and they're been striving to improve upon it ever since. Enter the G3, the third generation of hub-based power meters.
The G3’s design allows for a simple, straight-forward way to measure power. By mounting the strain gauges in an area where external forces, such as spoken tension, cannot impact power measurement, the PowerTap G3 is able to deliver +/- 1.5% accuracy ride after ride. More than just a powermeter, The G3 delivers speed, cadence and power with pin-point accuracy all in one product. And its ability to be easily switched between bikes means you’ll never miss a watt.

Great Training Aid
To be honest, all power meters do the same thing. This particular power meter is great and has been working for over a year with just one battery change, and it has never disappointed me with glitchy connection. I don't know if my garmin or powermeter does this, but it automatically calibrates when it connects which is great. Would buy again if I get a different bike :)
After almost a year and a lot of training the product seems and it is very reliable.From ride around to strong hits the accuracy is there to stay.Battery, simplicity (just go) it is really careless.I recommend that product to everyone that needs to training with watt.I still don't see the need to measure double sided, probably because i am not a pro but for sure it is one of my best value for money product in the expensive world(sometimes overpriced) of road biking.
