I use two Rondomatik only for the holiday season. The elder has no ventilation slots in the transparent cover. The newer already. Probably the manufacturer has been so trying to fix the problem of sticking by humidity. Whether with old or new or no cover, with me to empty no bowls. And whether flake, fine or coarse granules or tablets. With increased distance of 25 cm between the water surface and Futterautomat then more than one third of the bowl. Of the 28 bowls each so ever 9. And I have no increased humidity in the home. As a remedy, I have taken the Steward Rondo of HOBBY with heated feeding drum as this third machine. Great part, but can not be fed as varied by only a drum as with different bowls. So can not really be the solution.
