In this product category, I know of no better product. The application is simple, the service life when compared to similar products from other manufacturers large - between 4 to 8 weeks - depending on the use or rinsing number (800, according to packaging). Of course, the cleaning cube not spare the toilet cleaning, but this is much faster and easier. The price is certainly high, but when I compare the durability of other products, to get through the significantly shorter life at cheaper products but at the same price.
