“Really like how it matches my steel Relax bottle. I like the look of it better than the bamboo, and I love bamboo. Only giving four stars because sometimes it won't open when I twist it as it seems to spin around on the inner lining. Seems to happen when I try to open it right after removing it from the refridgerator, like it's too cold or something.”
“Got the metal cap to replace the original bamboo cap and this is a good quality, substantial cap that should last a long time. Very happy to have replaced the bamboo cap indeed.”
