Not perfect but the best product on toilet stains I've used so far!
It does remove stains but the shape doesn't enable me to scrub in some angles to reach a good portion of stains. Overall- it's the best thing I've used on trying to remove them.  I never thought a pumice stone would be a good idea for a toilet, but I get horrific hard water stains within 2 days of cleaning my toilet- the crazy blue drop-ins seem to stain it worse! I left for 5 days and came home to toilets that belonged in a &#34;Ghost Busters&#34; movie so I'll be buying more!  I broke one of them immediately, and used the other on 2 toilets that werent even that bad- so they do run out pretty quickly.  I'd rather have them softer and not scratch my toilet to ruins- so it's a trade off.  Wish they were a little longer/ bigger and would prefer a non-symmetrical end so different areas of the toilet could be cleaned easier, but I haven't found a better alternative out there, so I can't complain too much!
