The delivery was very quick and the packaging and the device in perfect condition. Curious what we have acquired since, we have the also the same in all versions that were important to us and are thoroughly tested at all levels with complete satisfaction!
Presentation and explanations are good and easy to understand. Already mentioned shortcomings, I could not tell from our unit - on the contrary. It runs much quieter than its predecessor. Disturbing noises we could not determine. Even with the temperatures we could find nothing derogatory.
This device complies in all areas of our expectations!
