From the spec sheet

Points for and against, drawn from the published figures — not owner reports.

In its favour

−45 °C trap and a stated ultimate vacuum below 10 Pa, both colder and lower than the VEVOR
Publishes its electrical requirement — 110 V, 60 Hz, 0.8 kW — which the rest of this brand's range does not
Drying area given as a figure (0.2 m²) rather than a tray count, which is how lab units are specified
LCD touchscreen with a PLC controller

Against

No tray count published, so the usable shelf layout is unknown
No dimensions and no weight published
Costs more than the eight-tray Blue Alpine Large Select while holding roughly half as much
Amazon-only brand with no manufacturer page behind it
