I went for cheap and regret it
When I opened the package I noticed these are smaller than the ones I am used to. They hold about 1.75 liter whereas my old one held about 2.25 l. I also noticed that the plug seals by squeezing the rubber body against the neck thread. I don't know if this design will hold up--it seems less robust than an o-ring seal. Worst, the seam on the red bottle split at the top corner the second night I used it. It could just be bad luck, but I have the feeling that these are cheaply made and I don't plan to try again.
