Have had my 330ml insulated bottle from a mystery brand for 7 years now. Paint is chipped and looks quite sorry in general, but I love it. I carry it around everywhere.
I also have a 630ml one from Quokka for very hot Summer days.
Lastly I have a 500ml Chilliβs for my job, which I also use daily.
For cleaning the bottles, I suggest using those tabs that are sold for cleaning dental accessories like retainers. If you use something to scrub them from the inside you can create little lines that end up catching bacteria.
