Chlorine Disinfectant Tablets 200 per Tub Creates a Ready To Use Disinfectant Solution x 6

I have bought these before and like all types of these tablets, they do exactly what is expected of them. My only beef is that, as often with Amazon, the advertised weight of the tablets is shown as 3.2gm when I fact they are only half that at 1.67gm. Obviously I'm a bit p***ed off, though it does clearly say further down in the product dilution and useage information, that they are only 1.67gm. Nonetheless, the primary advert is what most people will go by and that is self evidently incorrect. So BEWARE, the quantity is correct, the tablet size is not.
