The ASCOM issue is irrelevant and shows that the reviewer doesn't understand ASCOM. https://ascom-standa...FAQs/DevHub.htm is the replacement for POTH which got around exactly this problem for years and years.
Other than that, I find the review incredible. I am distrustful of anything posted on Fakebook. I personally have not ordered one of these and wouldn't until I see some reviews by people that I know are credible. Frankly, seeing finished products where one has no idea of the quality of the underlying data and/or the processing expertise needed to obtain the results, is just not something that anyone should be impressed by.
If I wanted to review a mount I would do it here or on other sites that have people who know mounts. I would provide logs and raw data. Without that kind of review, I'm not ordering one.
Still, if you don't own a mount, like the 30 lb capacity limit and understand the well known guiding issues, it would certainly be tempting to give one a try. Since I already own 4 mounts, I'll wait until I can see that one of the harmonic mounts is a good replacement for one of the other ones.
I wouldn't buy the ZWO version if there was even a whiff that it tied me into their appliance. Why bother with ZWO, when credible manufacturers like iOptron who have US based support are selling the same product at the same price? Think carefully about support when choosing a vendor. Mounts last a long time and so support is much more important than it is with guide cameras.
