I have 1 12,000 BTU and 1 9,000 BTU outdoor unit (multi U6RSL(2)-18), compared to the 9,000 BTU (on/off) Carrier Alegro that I had before, I think it is more powerful (that's the feeling I have), it is very quiet (only the air can be heard if it is set to high), it also has a swing function for the blades (both horizontally and vertically), for horizontal movement we hold down the swing button on the remote control for 3 seconds. For connection with a mobile application via Playstore, the Inventor application did not work for me (I couldn't pair the units with the application), the solution was another application from the Playstore (Midea Air) where I managed to pair both units (9 and 12) and it works normally (sometimes I have to close and reopen the application to see both units). I think Midea is the factory that produces Inventor. I have only had them for 2 days so I don't have an opinion on power consumption, reliability, etc. It has indicators on the body with a display that can be turned off with the LED button on the remote control. P.S.1 I would give it 4 stars but I removed one due to the Inventor application. P.S.2 I was impressed by how quiet the outdoor unit is, even though it is 18,000 BTU, it is almost completely silent! P.S.3 It has a self-cleaning function (I haven't used it yet since it is brand new). P.S.4 The Wi-Fi connection is only available for 2.4 GHz (not available for 5 GHz). THAT'S IT!!!
