Michael D.wrote a review of FSA Alloy PowerBox Power Meter Crankset on August 23, 2018
Familiarity: I've used it several times
I bought this in April of this year and by mid-June the initial battery went dead. No big deal right? Well I put in a new battery and then only got cadence data from it - no power. That's weird, so I reached out to FSA. Their response was that I needed to update the firmware on the crank. Seems reasonable, but the problem is that the only app they have to do this is for an Android phone. Since I don't have an Android phone I had to try updating when I was with some friends that have Android phones. Long story short, after emailing back and forth with FSA they concluded that I needed a replacement. I had to pay $80 to ship the crank to them so that they could repair/replace. Another week goes by and now it's mid-July. I am unable to pair with any of three different head units. Again back to FSA (via email cause there's no phone support). FSA says I need to update the firmware. So I try again to update the firmware (same song and dance, find a friend with an Android...). Unable to update the firmware. Now FSA tells me that I need to contact Power2Max the software company - that happens to be in Germany. Again long story short, they did their best, but I wasn't able to get that crank working either. So I got this crank on Apr 21, rode it for just over a month (10-12 rides) and I've spent the rest of the season trying to get it to work.
Kudos to Competitive Cyclist for agreeing to take it back outside the return window as a warranty issue - but I've lost the entire season of important training data because of this crank. Very disappointing.
