Krazy Klean Pro 3-Pack

Seems to work well

So far so good

Clean toilet

25 days and the toilets are still clean.

So Far so good

The product works as suggested; it does not leave behind any more rings, and the bowl looks clean. Need to hard scrub the previous line, though, thought a scrub sponge was supposed to come with the package. it would be 5 stars, but the product is a bit expensive.
