Okay, so I've been using this ketone breath analyzer for about a month now as part of my keto journey, and here's the real tea...

First off, the design is actually pretty sleek! It's lightweight and fits in my gym bag easily. The 10 replaceable mouthpieces are a nice touch - no gross sharing germs here.

BUT (and this is a big but) the accuracy seems... questionable? Like sometimes after a 16-hour fast when I KNOW I should be in ketosis, it gives me a big fat zero. Other times after eating some extra carbs, it shows high readings. Makes me side-eye the results.

The software could use some work too. It occasionally freezes mid-test, which is annoying when you're trying to track progress. And don't get me started on how many times I've had to re-pair it with my phone!

That said, when it does work properly, it's kinda cool to see the numbers change based on my diet and exercise. Just wish it was more consistent.

Final verdict? Might be okay for casual tracking if you don't take the numbers too seriously, but probably not reliable enough for serious keto dieters or athletes.
