Find that this works quite well on stubborn stains in the toilet, particularly the hard water stains. Definitely recommend.

I love this goose-necked toilet cleaner. Its fast, easy to use, and I get a great clean. This product cleans, deodorizes and also disinfects to 99.99% of bacteria. It is a thick gel which gets applied under the toilet bowl ring and it coats the surfaces. You let it do its thing for 10 minutes and then clean with a stiff brush. I love the 'spring waterfall' scent. I use this every couple of months in each bathroom because it gives a great clean - beyond my usual Comet. With our lined toilet tanks, I can't add one of those bleach pucks in because it would corrode the liner. The one challenge with this is that I have heard that the nozzle can be a challenge to operate because you do need it to squirt up under the rim: so far so good for me. Great price - great clean!
