Similar to the other two commentators, I am also interested in buying several of these air conditioners and have made enquiries with online suppliers in Switzerland and other EU countries. The last answer indicates that the suppliers all offer the same and latest units from Argo with 3.7kW (according to the argoclima technical data sheet). It is therefore surprising why Galaxus offers the units at a price CHF 1000 higher than other Swiss importers. I would rather buy from Galaxus but the price is simply not competitive.
