Which one did you buy ? The non carbon version is 3 bolt whereas the carbon one is Easton. If the seller has mixed it up, then they need to send you the correct one.

I got the carbon version...

I managed to open a dispute on the order, let's see how it goes...

Here are some negatives I've experienced:
- 2s+ delay, which is very annoying at the start of an interval when you don't yet have a feel for the power
- 1Hz update rate (similar to a Kickr Core, not per revolution like most other spindle-based PMs)
- Battery seems to drain relatively quickly

All of my indoor dual recordings looked fine, but I'm sure GPLama will find some issues. App is also alright.

All these sounds like serious issues to me...

From what I've tested, which hasn't been much, it's accurate when rolling steadily but has problems.

- The battery does not last as long as indicated; it drains a lot while in standby.
- It can’t read power spikes if they are very short, for example 1-second spikes. It only reads more sustained spikes.
- There is a small delay of 1 to 2 seconds in displaying data.

This is what I’ve been able to observe in the few rides I’ve done. I have it installed on my gravel bike with Riro carbon cranks.
