I guess it's ok, maybe it helps to keep our toilet clean, but the ones I received, they almost have no scents, very light. Also the tubes are only half filled, large empty spaces at top & bottom, compared to the pictures shown here which are filled full tube, so it's definitely not enough for 6 times. The first tube I used is only enough for 2 and half times, and no clicks when squeezing, so no ideas when to stop.
