VacplusAutomatic Toilet Bowl Cleaner Tablets, Bathroom Toilet Tank Cleaner (12 PACK), VA-T165Compact by Design (Amazon-developed Certification)

These things work great. The fact that individual units are wrapped in a dissolvable covering means you don't get your fingers blue when you drop them in the tank. They seem to last for a couple of weeks or more, depending on how often you flush, and the temperature of the water in the tank. If you're running straight cold water in the tank, they will last longer. The per-unit cost is quite low in comparison to similar products on the market, yeah it seems to work just as well. They have a nice fragrance and keep my toilet bowl clean below the water level.

Very easy to use! Just clean the bowl like you normally would then snip the package and let it drop into the corner of the toilet tank; doesn’t foam up so no worries about reactions! By the time you flush it later your toilet will be fresh smelling, and extra clean! You’ll find yourself scrubbing the bowl way less than you normally would.

W A R N I N GWARNING: Kohler, the manufacturer of our toilet, warns that use of toilet treatments will void the toilet warranty because of the danger that the chemicals in the product can destroy the seals in the tank and corrode the bolts that hold the tank to the toilet. In fact, that is what happened to the flapper in our toilet tank. We called a plumber who came and replaced the seal on the flapper in the tank. Then he showed us the label in the tank that stated that use of toilet tank and bowl cleaners (such as thd kind we used) would void the warranty on the toilet. That repair job cost us $95.00, but it could have been much worse had the bolts holding the tank had been corroded and destroyed and had the tank fallen off the toilet -because of the corroded bolts. Suggest home owners check with the toilet manufacturer for advice on what product to use.

These tablets make me smile i couldn’t wait to get them open and put in our toilets and now the toilet water smells nice and blue :) such satisfaction on Friday I will be purchasing again

They dissolve too quickly. Day, one after the first or second flush, the water is bright blue. Day two and three are decent, but by day three the blue is already fading. By day four and throughout the rest of the week the water is just a pale blue, almost clear, and it's been like that ever since. I think it's roughly day 14.. water is still a faint blue but I don't want to replace it till it's completely dissolved and after less than 2 weeks when it only looked the way it should for 2 days. Looking for another brand that will hold up for longer and actually keep my toilet clean and blue.

This is the first time I've tried this product. So far everything looks good and I don't have any concerns. The water is starting to lighter so I figure I'll have to drop another tablet in about a week. Its been 3 weeks since I dropped the first one.

It is so so so so blue. I was not expecting it to be that blue, but holy moly! It's definitely a dark blue color. I just put it in yesterday, so I can't attest to how it cleans. I'm definitely digging the color though.

I love these but they don’t break up well and they stain my toilet bowl a little but cleans off. I do love the way they clean… this is a reorder
