I used it for a couple of days, a good drinker but the capacity is small, on the 26th in the evening I connected the drinker, poured a full capacity of water at risk from the top, on the 28th in the evening the red light blinks, the water is on the bottom, I don’t know where 2 liters of water went in 2 days, before the cat I didn't notice such love for water. In general, the capacity is small, I would like more :)))See full review
