I hesitated in reading previous reviews ... and given the price I decided to try. No worries for me. All boxes have been delivered in good condition, all work ... and I was quite happy to quality for the price, they keep the empty days (I was even four days without touching it, the vacuum was still present).
Maybe I was lucky, but for me the investment was worth the wait! The small pleasant surprise to read "BPA-free" on the package insert.
