I had one of the original myo nozzles (when they were black silicone) and then upgraded to the clear one, but I had trouble sticking with it because I either had to reach into a regular water bottle to fish the straw and nozzle out (a concern since I can't leave to wash my hands every time I want a sip of water at work), or put the nozzle on the straw of a tumbler, but it didn't always fit, I'd forget to transfer it, etc. This new bottle has several improvements: it's insulated so I can keep my water cold, the straw fits into the cap so there's no reaching into the bottle to fish the straw out, and the lid has a cover to keep the straw/nozzle clean. And the bottle and straw disassemble to be easy to clean. The only thing I'm considering changing is swapping out the plastic straw for a stainless one of the same size if I can find one. As with previous versions, the myo nozzle is wonderful. I can feel (and see on my oura ring data) that I sleep better when I use it consistently and I have gone from not being able to suction my tongue to the roof of my mouth at all to being able to hold it there for more than 30 seconds with my mouth open (I can't remember the technical name of this exercise) so I know it's building strength. So far with this new bottle I'm able to stick to it much more consistently so I'm hoping to see continued benefits as I keep going!
