Verdict
OWC Mercury Helios 3
6 / 10 Expert Rating
Solid basic Mac eGPU box, superseded by the Helios FX which OWC still actively sells.
RIITOP OCuLink eGPU Dock
4.5 / 10 Expert Rating
The cheapest way into OCuLink eGPU, but a bare-bones product from a lesser-known brand with no built-in PSU convenience.
