We received one last Christmas. Use it regularly for beans and pot roast. The suggested cook times in the manual were a little too long though--and that matters in a pressure cooker. A couple minutes can make the difference between success and slop. 25 minutes for dry beans and 30 minutes for a decent-sized roast is more than enough time to get the job done. Fantastic job, Mr. Wang! edit: I'm just doing black beans.…
Also depends on altitude.
Apparently it's adjustable in their Ultra model: https://instantpot.com/portfolio-item/ultra-2/#toggle-id-15
