Can’t vouch for the case but the aerator is spot on. I have owned two (because the glass is rather thin) and have probably run 3-400 bottles of wine through then over the years. Works beautifully, much better than any others I’ve tried. Only downsides are the easy to breakness and that they aren’t the easiest to clean, but otherwise yeah.
If they are easy to break and hard to clean, what exactly makes them better than a more sturdy, easier to clean aerator?
