I bought two of these in 2013 and I love them. Wide mouth is easy for cleanout. Built-in handles for transporting or shaking up your wort to aerate make life easy.
I bought the 30L (7.9gal) and 20L (5.3gal) with the intent to use one for primary fermenting and the smaller for bottling or secondary fermenting. In hindsight, I would have just bought only 30L.
