I got a Brew-Boss as an early x-mas present for myself. Purchased the whole system, kettle, controller, pump and tablet. Simple to set up, the APP is great. Took me a bit of playing around to fully understand all the functions in the APP and how to set up my run just the way I want it. I am very happy with the system so far.
The day I received everything I set up, ran the wet run and couldn't resist brewing a batch of IPA. My AG day with my previous set up (keggle, burner and gatorade mlt) it was easily 6-8 hours. That first batch which i started at 9:30pm I was done by 2am. My next batch which was 3 days later I was clean and done in 4 hours. Then my last batch my wife dared me to brew on New Years Eve while we hosted a party. 3 hours, hit start as the guests arrived at 6pm and pitched the yeast 3:06 min later. I did do a lot of prep work and saved deep cleaning till the next day. But the system runs itself. Very little time was actually spent working the brew. I loved the fact that I could take the tablet into the other room with me and just hang out knowing that it would let me know when it was ready for the next step.
I have barely brewed in the last 2 years. Now I can't brew enough. I told my friends with keggerators to just throw me money for ingredients and I'll brew whatever they want.
If flexibility and automation is what you are looking for I definitely recommend the Brew-Boss. I have the 15 gallon system, which is great. I love that I can brew 5 and 10 gallon batches with no issues. I also feel the price is reasonable for an out of the box automated system.
