The listing currently states: Window slide Measures: 650mm to 1200mm Max. However, this is incorrect. I have a window that is 750mm wide. The design of the window slide means that it cannot fit this size of window: the exhaust vent obstructs the window slide from adjusting to this size. I have had to cut approx. 100mm off of the window slide. I wouldn't expect to have to do this based on the description.

Started off ok, but has become very inconsistent as to whether or not it actually blows cool air. The exhaust attachments aren’t particularly secure - I used duct tape to secure both ends of the hose to the relevant parts, which seems to have improved the cooling/airflow. Honestly disappointed considering the price.

It arrived while ago but the weather was cold so I waited to write my review. About APPLIANCES ONLINE: I'd like to remark that this is the second time I buy from Appliances Online and the service I've received is once more EXCEPTIONAL! Starting from the adjustment with the price I had with the Chat from the shipping arriving Punctual like a Swiss made watch! I warmly... no.. hotly (: ahah:) I recommend Appliances Online! About OMEGA ALTISE I have very old windows and a home made fly-screen so I was very preoccupied about how to install the hose outside there. The Aircon arrives with a very simple ingenious accessory that is extendable and you can adapt for every sliding window you have! I didn't have any trouble to fix it! The Altise does dutifully its job and you can just get off with the fresh air at the desired temperature (from 16º to 32º I think). It comes with its Remote Controller which is very manageable. I've been using it for only 2 days however, but the premises sound good. The low watts are hopefully not indenting my next bill!
