Awesome product.

The unit was more quiet than I thought it would be. Nice sleek design. Work great at cooking the house. Just wish there was tidy looking window kit for a push out window.

Strong air conditioner

Great size air conditioner and easy to move around. It seems much stronger in capacity than the other ones we have had so far. We have tried the coolest setting at 16 C which seems to get the room very cool in a few minutes. Hopefully it will work just as well during heatwaves.

S-290 Air conditioner

Very powerful AC Unit, cools a large room very quickly.
The fan mode is also a very useful function if you want to cool yourself or your dog down very quickly.
Not tried the dehumidifier mode yet so cannot comment.
I have communicated with customer support about understanding how the AC unit works and they were first class.
