What a really good invention at low cost. Your aquarium fish are provided with a weeks supply of food, which means not having the hassle to rely on friends or family to have to go in daily to feed fish.

Extremely happy with this product, lasted well and fish looked happy on return, initially concerned for catfish but they were okay too. Would recommend this item.

A total waste of money, did not dissolve after four days only bits of the coating clouding the water. Removed and threw away. Glad I tried it before going on hols. for two weeks. Definately not recommended.
