I bought this product to better understand my cycle and support my fertility journey, and I was honestly impressed. From the very first month, I was able to clearly identify my fertile days thanks to the accurate and easy-to-read results. I also loved how complete the kit is!!

Technically it works, but it is soooo cheap, the lens fell off the first day, it was glued on really poorly. And the light mechanism is so finicky, it doesn't work how it’s supposed to at all. At the time of purchasing this, this product was the only ovulation microscope available, and too bad because it’s very low quality. I will be looking for another one thats made better.

It does what it’s supposed to do but it is extremely cheaply made with flimsy plastic and it is difficult to turn the light off. I do appreciate the extra batteries being included. The packaging had clearly been open, however, the item appeared unused so I did not return it. Shipping ended up being much later than it was promised to be delivered by.

The light inside died after 1 week, rendering it useless.
