What advantage can a stainless steel container have compared to its much cheaper plastic and glass counterparts? There are multiple reasons why many people switch to ss containers, including myself. One of the most important advantage of them is that with good cleaning they will last forever. This makes them highly resalable or a good family heirloom. Compared to plastic fermenters, they are harder to scratch and can be cleaned more easily. Compared to glass, they are not prone to shatter, which can prevent injuries. The biggest disadvantage they have is the price. Luckily in the last years a few, more budget friendly products were released to the market.
