Review on 12-Pack Vacplus Automatic Toilet Bowl Cleaner Tablets, VA-T165 – Effective Bathroom Toilet Tank Cleaner by Jennifer Stevenson

Actually I didn't expect it to work. He couldn't remove some of the stains on the bowl by himself (yes I'm lazy) but after I cleaned them myself he wouldn't let them come back. Because of the hard water I'm used to spots here. I usually have to clean anything that comes in contact with water at least once a week to prevent stains. A month has passed with this blue puck and there is not the slightest trace of a stain. I don't know how long it will last yet (it looks a little smaller than when it was inserted, but not by much) but given the price per puck I think it's definitely worth it. Not only does it prevent limescale stains, if you know what I mean.
