4 stars for how awesome this thing is at cooling down a room and how Easy the set up was! But this thing is way too loud. It makes this really loud and annoying buzzing noise that you just can’t shake! I mean it’s one thing for it to make noise because it is an a/c, but my other portable a/c that sticks out my living room window is not nearly as loud. I just bought it and am debating taking it back, but I’m in love with how cool it gets my room, it really does work great I just wish it didn’t make that buzzing noise all night when we’re trying to sleep. Idk works great but I feel like they could’ve made it less noisy for that much money.

Perfect comfort, year round!

Our Toshiba has been great for 4 years now, no issues, and keeps us nice and cool on the hottest of Summer days, and snug and warm during the cold Winter nights. The add-on Wi-Fi has been great to turn the unit on and off remotely as well as setup different schedules.

Does the job

So far so good. Not for a very big space but works well for the bedroom.
