I've been super happy with my Favero Assioma Duo's. Key point? They've been completely hassle free and 100% reliable. I've had them for about 9 months now and haven't had a single day that they wouldn't connect to my Bolt or Trainerroad on the PC. They've also never given me suspect power data despite the fact that I almost never calibrate them. Battery life is so long that its almost a problem, because I don't charge them regularly. In fact the only time they have failed on me was when I forgot to charge them before a race after like 3-4 weeks of not charging them. I actually bought them with the intention of switching them between my TT bike and road bike, but now I hardly ever do, as most of my training is on the TT bike anyways. However, it only takes <5 minutes to swap them if you need to.

Some people complain about the look of the pod, but its barely even noticeable once its on there.
