I love my PicoBrew. We've made over a dozen recipes, with an IPA slated for next week, plus a few sous vide sessions. It takes the tedium out of all-grain brewing, not to mention a complete elimination of boil over messes. The company has been very responsive to troubleshooting, and their recipes tasty.
I'd probably never do an all-grain beer in a kettle; I don't have the time or inclination to watch water boil. But I'm happy as heck to try crafting my own recipe with the Pico.
