For an all in one system it is by far and away the best available in my opinion. You get what you pay for. I was a grainfather user (G30) i have friends that use brewzilla/robobrew etc. Nowhere near the quality as this. The G70 grainfather is a disaster for the price tag.
The brewtools use of easy clean TC fittings, the valve system, the software and touchscreen ( that can be removed and placed on a wall if you wish). They are constantly working on making the system better and better. a new lasercut false bottom. Mash overflow pipe and soon a trub trapper to make cleaning easier as well as maximise clean wort into the fermenter thus increasing efficiency and less waste.
The unit is CIP which makes cleaning a breeze especially with the CIP spray ball.
I have done 27 brew days with this unit and have no issues with it.
Those considering buying the B80 which i would recommend as you will future proof yourself as you will want to brew more beer with the same time you spend brewing a batch. You will need two 15 amp plugs installed for max power. I would also recommend a hoist of some type to lift the basket with large grain bills. Though you would realistically need this as well with a G70 or large brewzilla/robobrew anyway.
I hope this helps
