Bought 2 units to get installed at in the bedrooms. Moderate sized (4x4m) rooms. Easy installation with the electrician. Unobtrusive looking unit inside and out. Now up and running and cooled the rooms easily, despite the 39degree temperature out size. The process for setting up timers and air direction was very easy after reading the manual. The quiet mode is actually noticeably more quiet than the lowest fan mode. Would recommend.

Have only used the cooling a few times so far. This is a 2.5kw and it is quiet and cools our bedroom quickly. The outside unit was installed on brackets and the whole process took 2.5 hours. 5 year warranty on this model.
I know it's early days for a proper review but I will update if I need to add anything.

We bought this brand new panasonic air conditioner rather then buying any cheaper one thinking it would give a good service for at least couple of years. But after using for a month (of course not everyday, may be 10 days the max) it doesn't blow cool air. Its the pick summer now (42°C in the afternoon) and I have a new born. We complained and they said it will take 2 weeks to come and see. I even told them i have a new born (as if they care). Now i go to mall or other places and stay the day with my baby. What can be a worse experience than this?

These were sold to us by a large retail chain in Queensland who seem to be selling heaps of them.
I've seen plenty of new air cons including Mitsubishis and Daikins. These Panasonics are very cheaply constructed. The plastics are very thin and the wall plate is about half the thickness of a Mitsubishi.
5 year warranty, so its a good budget brand but definitely not a quality AC like some of the bigger brands.
Do yourself a favour, download the brochure and compare with a Mitsubishi or Daikin. The soundlevels, air volume etc are all better. The noise output on this 2.5kw is 62dbs! almost twice as long as other brands which are around 58dbs. Also the energy rating is only when using 'EcoNavi' setting, so its not all the time.
