sorry to tell you that, but as you can read here in the forum, there are a lot of issues with the aquaero and in general with the controlling display device.
...
We sold several thousand aquaeros and get only a small amount back for RMA. A lot of these aquaeros were damaged by the user himself. We also had a handful of customers in the past who damaged two or three completely new aquaeros within a few days. In my opinion it is obvious that there is a problem with their system or they are doing something wrong.
You should also keep in mind that only customers with problems come back to the forum while people that are happy do not. Of course it generates the impression that there is a major problem but from this point of view you have this with almost every product on the market with higher sales.
