### ⭐⭐⭐⭐⭐ A Year-Round Essential: Effective Comfort with Convenient Control!
*by E***E on March 14, 2024*

Our nursery is situated on the second floor, facing away from the morning sun. It gets pretty chilly in the mornings, especially when winter sets in. With just one vent on the upper level, our heating system was struggling to keep up. We were considering either installing a second heater or finding a more effective solution.Luckily, we stumbled upon this fan booster, and let me tell you, the remote control it comes with is just fantastic! So convenient! I can adjust its settings without even leaving the cozy comfort of my bed. No need to get up and fiddle with buttons, just a gentle press and we're enjoying a warm, comfortable room. The remote for this fan booster is designed with such user-friendliness, making it a breeze to stay cozy and convenient even in the chilly California winter.This fan booster can get a bit noisy at its highest setting, but compared to a window AC, the noise is minimal, especially considering the warmth it provides.I can only imagine how handy this fan booster will be in the summer months! We're expecting that cranking it up to the max, along with an extra fan, should keep the room at a comfortable temperature, possibly even cooler than the scorching California heat outside.Overall, this is a practical product that works year-round. While it won't instantly warm or cool a room, if you're looking for cozy warmth in winter, refreshing coolness in summer, and a simple, cost-effective solution, this fan booster is definitely worth a try. Kudos to the company for providing such a practical product!

### ⭐⭐⭐⭐⭐ Remotes other than the original can interfere
*by J***H on June 23, 2025*

I love this as I moved into a small room with the in laws and they keep the temperature higher than I like. It keeps the room cooler than the rest of the house by atleast 5 degrees or less. Only issue with the unit is my fire tv remote when turning the volume down shuts off and on the unit. Be careful with other remotes in the same area. Function is great but accepts signal from other remotes!

### ⭐⭐⭐⭐ It works
*by A***P on July 21, 2024*

Gave this 4 stars because it's not life changing, but it does work and has helped balance the temperature in the room it was installed in.Our master bedroom is on the second floor (furnace is in the basement), and on the opposite side of the house from the unit, so we've always struggled with the bedroom being the warmest in the house during the summer. We've been using this fan for the last month (of mostly 90 degree days) and it has made sleeping at night much easier without the need to adjust our whole house thermostate.
