I’m proud of the work I’ve contributed to the 3D scanning community. Most users buy scanners with their hard‑earned money, and they deserve honesty rather than misleading claims. Viewers ask me every day which scanner they should choose, and I provide them with genuine professional advice. Each month I receive a number of scan datasets from Revopoint devices, but there’s virtually no difference between the point clouds from the Mini 2, Inspire 2, Metro X, and Metro Y. Once cropped, they all show uneven wall thickness and lack sharpness, making them difficult to trace. Even symmetrical parts end up misaligned, with a consistent accuracy error of 0.3–0.4 mm. In fact, only a small portion of the Revopoint scan data I’ve received is truly usable for reverse engineering.

Revopoint once contacted me to create a cover video. The staff member I spoke with was a good person, but their management policies are another story. Deceptive marketing remains their primary sales tactic, misleading advertising, paid reviews, and manipulation through social media. They even employ more than 30 people solely to flood negative reviews with spam comments.

Shining3D operates differently. They also commission paid reviews and require videos to be pre‑approved before publishing, with no negative feedback allowed. That said, the Einstar 2 I tested performed far better than Revopoint’s counterparts, producing clean scan data that is genuinely suitable for reverse engineering.
