OK got it a few weeks ago.
Tried it with my Android phone (Pixel 8 pro) and it did not work at all.
It took countless attempts just to be able to connect it and then the connection drops all the time. I could not really get any reliable recording.

Today I gave it another try on an iPad. This time I have been able to connect right away and I can even do recordings which is a better start.

Trying that at rest, it gives me 100% fat burn and 0% carbs burn as it should be because I’m at rest.

So far so good now the issue is that when I start a recording it instantly gives me 0% fat burn and 100% carbs. I tried several times to turn on and off the recording and each time I get the same 100% carbs(0% fat) burn in recording mode and 0% carbs (100% fat) burn in non recording mode.
All that at rest and not moving.

Clearly useless currently. Maybe @Calibre will be able to fix that in the future.

Any update on this? Anybody else get one and get it working? So far I’m not seeing much positive feedback. Particularly looking for insight on Vo2 max.

I’m veteran amateur 53y old cyclist . But have loved this sport since my teen , beginning with BMX at international level. But since my 20ties been mtb and rdbiking. Just to give you some context about me so have read a lot about VO2max. But will be doing a Peak VO2 test with the calibre one of this days and let you know.

This pic is the ventilatory rate, I can see my VT1 clearly,
This ramp was till my FTP power. Will do another next week above FTP to see what happens.
Cycling with the calibre on the mouth/nose is comfortable, but it shift some and make breathing sometime dificult. I think for athletes there must be another mask for this kind of test. But if you ask me my honest review, this thing works.
