We have been using our roaster in a production environment for 3 months and are extremely satisfied with the value-to-cost of the Artisan V Roaster. We can consistently roast back-to-back ‘super loads’ (over 5lbs) with little or no trouble (after the heat shield upgrade). Ken and the folks at Coffee Crafters are always available to talk and are ready to incorporate suggestions for improvements into the equipment. We have found it VERY easy to service (yes we have had several significant problems that were solved with the heat shield upgrade) and even the most major repair can be made by any reasonably savvy roaster-owner. We plan on buying a second roaster this Fall.
