If you have money, then it is definitely better to buy this flask than a cheap plastic version with a twist flask, which is without a drain hole and with a blind twisting of the cartridge inside. Such a flask has been standing for 3 years already and no problems, while the neighboring plastic flask has already managed to change one, for some reason a microcrack appeared in the plastic.
I have included some photos in my review to provide a more well-rounded assessment.
