Good quality and appearance however I feel that saying that it has 3 months life is a bit on the high side. From my experience, 2 months is much more realistic. Anyway, usage will depend on how often the toilet is flushed. Also, it doesn't really remove stains, more like cover them up with blue coloured water. The only ingredient that can remove stains is bleach and I don't think this product contains any bleach. Otherwise, it's a convenient way to add blue to the toilet bowl after every flush.
