Femfresh?

Does anyone know if products like femfresh or any similar sprays are any good?

Generally I'm fine but I've found at work, if I wear tights or jeans which is pretty much every day it can get a bit smelly down below. I think because I spend 8 hours with my legs crossed sat at a desk 😕

But its really annoying feeling smelly. And its just not as comfortable to spread my legs aha. It's only after work as well any other time I barely smell.
