Bests & Worsts Reviews from Amazon

I am leaving this review in hopes that it helps others. I love this product. I really do. Well made. Easy to transport, clean, and keeps drinking cold for a long time. But I just discovered that this product triggers a migraine for me. This might not affect everyone the same way. Let me explain. I typically get what is called altitude and barometric pressure migraines. After I began using these, I suffered a migraine daily. We could not figure our what was going on. I checked what I was eating and drinking. Healthy, yes. Water, yes, in abundance. Water bottle? No it couldn't be that. Yep, do you research. Apparently for some people stainless steel water bottles can trigger a migraine in some people due to the leaching of nickel and other materials. I stopped drinking from this water bottle...and migraines resolved. Scary. Very scary. From now on GLASS ONLY. And only when the material PABA FREE. LifeFactory is my next option.
