100x 2g Espresso Machine Cleaning Tablets Espresso Maker Descaler Coffee Machine Cleaner Tablets Descaling and Cleaning Tablets for Coffee Maker Pot, Descale Drip Coffee and Espresso Machine

Theres so many! I think this will last for the rest of my life ha.

Ordered this Heigble 100x 2g Espresso Machine Cleaning Tablets Espresso Maker Descaler Coffee Machine in order to try to descale a older Keurig coffee maker that had quite a bit of visible scale building up and had stopped working until I banged it. So I figured I would give these a try. White vinegar had worked ok in the past.. I tried two tablets in the reservoir that makes about 8 cups of coffee.... that did very little after making 5 cups and sitting for about an hour. Frustrated I put in half water and half white vinegar and then 3 of these tablets and made another 5 cups of coffee... it started to work and a lot of scale and gunk was dissolved. I am not experienced with other tablets so it's hard to rate these. It would be nice to know what volume of water corresponds to one tablet...I still dont know.The tablets are well packaged in 10 boxes of 10 each, that is nice in a way if you want to share them with people but after a quick search think that contributed to the price of this item being higher than say a single tub of 100 of these.Hard item to rate so went with 4 stars as I do think it did something. Hopefully my rambling review is helpful in some manner. I don't know if my machine was just extra dirty or the product needed the white vinegar to really work well... or if I just needed to use more tabs.

Works to properly descale and clean a machine. Was able to clean two coffee makers with these that I've never been cleaned except with vinegar water, but these tablets actually clean the stains in the carafe.
