I wonder if all the good reviews were only made spontaneously, or whether they would even yet after 6 months: I had broken two of those things, and they were both after 4 months. If they work, then they are really good, but keep a little longer, they should have. My conclusion: eyewash and ultimately cheaper scrap China, which produces only a lot of trash here. PS: please Flag anyone here, in which the thing has held for more than 1 year.
