From what 4 owners described in owner discussions between February 2022 and January 2025. Studio (SL100) owners only; reports about the older Steak Locker Home and Professional editions are excluded.
Forty pounds of bone-in rib roast across four shelves is the biggest load an owner reports, and the owners who have run it are happy with it: one calls the flavor difference worth the money, another has aged a number of steaks and had one at 42 days and counting, and a third says it works fantastic.
Getting started takes some reading, because owners find the manual thin. One owner learned more from the maker's blog posts than from the manual, and bought the Wi-Fi controller separately. Compared with the dry-age bags that owner used before, the Studio gave noticeably more tender beef.
