After my older Stages quit working I needed a new powermeter. Got a really good deal on the 4iiii and it does a really good job. The only problem I have is, I wished I had purchased a dual sided unit. But at 68 it was hard to justify the xtra cash output.
For what I need, this fits what I need it for just fine.
Much cheaper than the other options. Seems just as accurate. Very quick install. The 4iiii software is kind of janky and doesn't like you to pair two products, but once installed, you don't really have to use their software... I go through my Garmin head unit. Spin the crank a few times and it pairs right up to the garmin. Have yet to see the battery life, but I am am a few hundred miles in, and have not had any issues. I am using this on two separate bikes and not having issues. The third bike has Garmin Rally pedals and I don't see much of a difference in the ride numbers as recorded by any of them.
