Ordered 3 bottles, 2 of which had been ordered with specific engravings requested. The order showed up with no engraving on any bottles. The packing slip showed the engraving line items yet the order was still shipped. No contact if there was some sort of issue either. This tells me the order was shipped full well knowing it wasn’t correct. Lazy? Yes. Negligent? Yes. Terrible customer sentiment? Absolutely. Not pleased and waiting for Miir to make up for this let down.

Works excellently except it is quite difficult to tell if it is opened or closed and if you drink from it at the wrong spot you will get flow from the other sections.

Simple design, but not without its flaws

It's well-built, and overall, is a good, simple design. However, there are a couple issues with it. First, it's effectively impossible to tell if it's open or closed at a glance. You can give it a little shake, and you'll hear a little rattle from the cam switch (or whatever piece makes it work). You can search for the subtle little line that's visible when it's open. You can try to pour some liquid out. But it's not a "quick glance" kind of thing. Which has lead to me spilling water on my car seats twice in the week I've had it. Second, the design of the gate means that while you can sip from 360 degrees, you're never going to get a lot of water flowing, and it acts like a bit of a baffles, so the water doesn't flow like you would expect. You can get used to it, but you have to get used to it. Oh, and the gap around the inside of the lid, where the water flows out, like to collect... stuff. Dust, cat hair, crumbs from breakfast, whatever happens to fall on it. Easy to clean, but still. Gross. I'll likely purchase a chug lid at some point, as I don't think this one's really for me. It's well-built, though. I don't foresee any way this could fail or break, at least not easily.
