Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I have one and it's well worth it. Anyone that says it's inaccurate doesn't have one.
Plus to be fair even icp tests aren't fully accurate.
Your looking for trends and doing 8 tests in 2 minutes is a no brainer. Especially if you have multiple tanks.
Highly recommended - but very expensive.
