I've got one in the fermenter (Hefeweizen) at the moment and another waiting to be done (Clearwater Light Ale). So far I've had no issues at all, the recipe is really easy to follow and made for the GF. Everything is sealed absolutely air tight.
I opened mine today, very excited to say the least!!
There have been quite a few adjustments from the previous Robobrews I have seen in pictures and on YouTube. Mine is without the pump as shown in the picture above.
Bring on the weekend so I can get a brew down!
