I have this model, put ice and only can lower 3 degrees, and the water container can only open half that restrict you to put more ice bottle. This model is not recommended, better buy 3 panels honeycomb that can lower by 3 degrees without putting ice, if put ice, lower 5 to 8 degrees. Recommend Clarte 729 where you can open up the panel and put ice bottle easily, and price is cheap 2500 baht.
