We liked the SMART features of this unit, which does a good job of cooling off our master bedroom.  However, the unit makes a lot of noise--not the fan noise, which doesn't bother us, but it makes a grumbling/rattling noise that's not associated with the compressor coming on.  Also, the bluetooth connection drops daily, requiring a re-sync of turning the unit off and on and re-syncing, which doesn't always work for some reason.  Finally, the hose connector to the unit isn't airtight, so a lot of hot air is escaping from that area instead of going out through the hose.  Our condo actually has a port for portable a/c units to connect hoses to; you just remove the grill and filter and the exhaust end of the hose fits directly onto it, and that seal is airtight.  But the connector that hooks the hose to the unit is not airtight.  

That being said, it does cool the room, so it's adequate.
