Good idea but not intuitive & low participation
I bought the Pearl S to make the most of Brewguides but have found it disappointing. I have not found a speciality coffee roaster that uses it in the UK. The only guides available are the standard Acaia guides. With greater roaster participation it would come into its own. Making your own brewguides is not intuitive and is slow. The transfer process is also slower than you would expect and the way the scale displays the guide is a bit confusing, sometimes requiring interaction, sometimes not to move between steps, I’m sure this can be changed but it is not clear. I have reverted to using the scales in timer / weight / flow rate mode which works best for me.
