I've been using a Wahoo Elemnt Bolt with the Wahoo speed, cadence and heart sensors since March of this year (2020). On the whole I really like the head unit, but over time I've been encountering an increasing number of issues.

- The heart sensor started to malfunction after only a few months and had to be replaced under warranty
- The cadence sensor started to malfunction after 7 months and had to be replaced under warrany
- Now the elevation readings on the head unit are totally inaccurate

With regard to elevation, I know accuracy is an issue with many head units. However, my Elemnt Bolt went from giving me elevation that was "in the ballpark" to elevation that is inaccurate by thousands of feet. I'll contact tech support today to see what they have to say. I have to assume this sort of "drift" over time (at least to this extent) is not mormal.

Anyway, I'm curious if this is par for the course with Wahoo or if my experience is more of an outlier? I'm also curious to know what (if any) head units/sensors would be significantly better in terms of accuracy compared to the Elemnt Bolt. Thanks in advance for the feedback!
