It shows variation of tests results throughout my family members...which I think it is reflecting good. More importantly, it's affordable and helpful.. going forward on my next purchase.

Great value for the price

Great

The readings on this strip are consistent, which is a good sign, and they show me consistently lower than a competitor's strips.....and those strips are also consistent. With these strips, I am almost always in the low to threshold area...in the strips by HumanN...I am well above low...either right under or right at optimal. So I don't know which is correct...I use them as control test. I will say this, Super Beets has raised my NO2 levels and greatly reduced my blood pressure.....and taking that supplement is why I got the test strips.

I am not sure they work. Every time I use them the strip reads as VERY pale pink (which means depleted). However, when I tested using a sample strip from somewhere else it showed threshold colors. So Maybe they are more sensitive or... they don't work.
