no reviews? sketchy
There is a review by GPLama on YT... two actually.
I also have a unit and more or less the conclusion is similar: for $100, it is great. Built quality is great, how fast and reliably it connects to my Garmin Edge is flawless, charging port is better than the 2-pin magnetic connector that is almost universal between Magene and Xcadey etc spider PMs, battery life is great.
The issue is that the power readings have a tendency to drift a bit after hard efforts.
I do not know if this is a Firnware fix away and when this is happening, but it is persistent. It is a few % off, it is not unusable, but worse than my Favero pedals or 4iiii single sided crank PMs.
Still, training or racing even with a PM is a huge improvement, even with less than perfect results...the price point is impressive and I would recommend this even of it is not ready to "destroy" the market of $300 left side crank PMs or $600 pedals...
Just pay attention that it says that it is not compatible with a modern Shimano road chainrings. Yet video shows switching 105 just fine. I'm very confused

Yeah I'm gonna stay in "wait and see" mode on this. It is nice to see prices on power meters coming down though- I'll have to keep an eye out for one with good reviews I can take a flyer on.

I have purchased and successfully installed it. I didn't see any note stating it is incompatible with Shimano road chainrings.
