It rusted after two days of use!

Very nice at first, but it did not hold up after many shakes with ice inside. The strainer broke. Whoever buys it should avoid using it as a shaker. Nevertheless, mine has not oxidized at all

After its first use for making espresso, the material started to oxidize. Unacceptable for a product intended for health use... Give something more for something that will at least last.

Together with this shaker, I also bought a small one. Unfortunately, my large one came with some dirt that looked like rust. No matter how much I washed and scrubbed it, they wouldn't go away. It's probably not rust since it's stainless steel (I think), but just seeing them and not being able to remove them with cleaning, I decided not to use it.
