45 mentions across 3 sources · 32% positive — critical (weighted across 3 sources)
YouTube, App Store, Lemmy
What users praise
- • Fifteen-plus years in restaurant automation gives Presto real QSR operational experience
- • Handles POS and headset provider integration itself, avoiding a lane shutdown at install
- • National rollouts at Wienerschnitzel, Taco John's, and Dairy Queen validate enterprise scale
- • Spectrum-of-models approach targets store-by-store variation in menus, accents, and ambient noise
What frustrates them
- • No independent operator reviews exist in the public data to validate the 95% claim
- • Vendor-published metrics lack third-party audited baselines or methodology
- • Only Toast is named as an integration — other POS stacks are unproven
- • Pricing is undisclosed, making per-lane ROI modeling impossible up front
