In auto mode, each unit provides air for your home at your desired comfort level. Set your desired temperature, and the HVAC unit will determine how much heat or air conditioning is needed.

If you desire to keep a room quiet and minimize lighted alerts, you can mute each indoor unit. By muting the system, the buzzer for alerts will not sound and the LED lit display will turn off. Should the unfortunate event of a power outage occur, the MrCool system will automatically shut off and then back on with the same settings once power returns.

Just what I needed for my home office
Color: White, Color: White
My desktop is an old butcher block so I opted to use the screws. It was fairly easy to install using the measuring strip that was provided. The holes you drill don’t have to be perfect because the net has elastics that you can tighten and also keep from hanging too low. The net is not visible when standing. For wire organizing the net works best for me since I travel for work and have to unplug my devices often. It keeps the floor clear and easier to clean around.

Great product!

I would definitely recommend this product as it works as intended. The net doesn't feel cheap and it seems durable, in my setup it was just what I needed so I am happy with this purchase.

Simple and sturdy!
Color: Black, Color: Black
I really like this product. My desk is just a regular table, so I wanted something to hide by bulky laptop and monitor adapters, and this does the job perfectly. It gets everything off the floor and out of view. Plus, it comes with some bonus Velcro cable ties and adhesive cable clips to help further wrangle cable chaos. I was hesitant at first because of the price, but it’s clear that it is a sturdy well-made product. The mesh is finer than other slings I’ve seen, so cords and other things won’t get tangled in it or fall through. I didn’t end up screwing the anchors into the table like you’re supposed to; I just used some large adhesive cable clips instead, which seems to work for now. I’ll probably end up purchasing another one for my partner’s desk.
