I gave this item 2 stars because of the high price ($23.50) and low quality.
It is made of too thin of glass for the money I spent on it. This is especially true on the bottom. It seems so thin on the bottom that if I were to tap it really hard with my finger I think it might break. The glass in general is so thin I doubt I’ll go long without breaking it. Also, the base is not perfectly round but it’s not noticeable without close inspection. The only bowl I have tried in it comes from the 'Black Leaf - 8-arm Tree Perc Precooler - Recessed Joint' and it fits well. There is a very slight wiggle too small to see but the seal is air tight (not that this is important on a bowl holder).
