Elos PO4 Test kit.. Anyone use it?

[ooja3k]

I am looking for a PO4 test kit, and I found the elos one. I love their alk, calc, mg, and no4 test kits, and would love to try the PO4 kit as well.

Does anyone have any experience with this kit?? it says it reads down to .01 This would be a good test kit right??

Thanks in advance!
