Well, I’m not super impressed. I mean it arrived quickly but (for me, or in my opinion,) it is not the easiest little contraption in the world to use. After a couple of “uses” it’s been showing errors and I don’t know it just frustrating. And then to find out there’s not that many strips that come with it and you would have to spend a small fortune if you were testing pretty consistently. I would really like to return it, but I’m fairly certain I no longer have the box and I’m not sure they would accept the return. (Understandably) I just got some “keto stix” from Amazon. That’s good enough. Lol. But, if you’re handy with these little contraptions, and good with the amount of those strips, then I’m sure it’s a great little thing!
