4iiii PRECISION 3 Powermeter

Whether you are fighting for a Kona slot, spending countless hours on the indoor trainer or striving for a personal best; one thing we know, success takes time. With up to 800 hours of battery life, +/-1% accuracy and weighing in at only 9 grams, the PRECISION 3 Powermeter will be your trusted training tool for years to come.

I heard a lot of good stuff about the previous version of this power meter. Unfortunately, in order to extend battery life (I guess), this version is constantly going to sleep mode as soon as you stop pedaling. And it needs a few seconds to wake up, which means every time it goes down, you lose a few seconds of important data. Very disappointing.

I bought two of these only to find out they do not work with Garmin Edge 1040 because of incompatible ANT+ frequencies. Garmin says 4iiii must fix it. Is that on the way? For now I have no functional power meter.

Would not buy another one ...the plastic cover on the right hand crank is crumbling and battles to hold the crews that secure the battery and the right hand ones battery sensors have broken off so it gets not power ...shocking for an @sworks @specialized Tarmac ....waiting to see what Specialized do to sort this out but I am not holding my breath that it is going to be a positive outcome for me ...this power meter is about 12 months old, which to be honest just shows a substandard product aggravated by the reluctance to sort it out like most premium brands would do ....dont buy !!
