Pricey, but worth it
I got these to go with my natural cycles thermometer and app(10/10 recommend if your are trying to track naturally!) it got here quick, and I think itโs super easy to use. It takes 3 minutes to check to see if your LH has risen. Iโve had a couple funky months with high stress so my cycle has been a little off, but using this to track ovulation has been great. Iโve used it for about 3 months now, off an on based on when the app suggest to check. Itโs been pretty accurate. I think that for the money itโs a little pricey, but it does offer ease of mind knowing when you are fertile and when you are not. Battery life is great, and overall great quality!

Easy and accurate!
Definitely recommend and is very very accurate. Super easy to use, just like taking a pregnancy test and is a great deal. Way easier to use than the traditional lined strips.

Worth it!
Really love the simplicity paired with the natural cycles app. I have used other ovulation tests but these are worth it if you use natural cycles.

Strips dont work
Out of 15 only 5 strips worked so far and all other of the strips when inserted read to try another one. PS, the packaging mentioned expiry date of 2026 so it feels I wasted so many strips, time and money. Since, the brand was recommended by Dr. I didnt even feel had options. Due to initial days failure itself , I started tracking with other company strip as well and was able to see, report progress. But this one kept failing every day. Since I had to use to product in hope for next one working and reporting per Dr. Instruction, I cannot even return and I hardly write review so even this feels I am being critical but I hope you make better decision after reading it or the company improves the quality, cz well what is amazon going to do for substandard products?
