What users praise

  • • Named deployments at Wienerschnitzel, Taco John's, and Dairy Queen provide reference-able scale evidence
  • • Installation handled without disrupting live drive-thru lanes removes the biggest rollout blocker
  • • Toast Partner Ecosystem integration as of September 2026 broadens compatibility for Toast-based brands
  • • 15+ years in drive-thru automation since 2008 gives Presto unusual domain tenure

What frustrates them

  • • Zero authentic community feedback exists in Reddit, HN, GitHub, Product Hunt, or Stack Overflow
  • • All headline metrics are vendor-published and unaudited by any independent third party
  • • Pricing is contact-only, making ROI modeling impossible without a sales conversation
  • • Voice data handling and retention policies are not publicly documented or discussed
