Customers find the space heater effective, with its 100° oscillation feature spreading heat well and heating up more than 200 square feet.
I got this space heater for my bedroom, and it’s been working really well. It heats up fast and warms up the room quickly. The remote is super handy, so I don’t have to get up to adjust the settings. I also like that it has a timer, which is great for bedtime. The heater feels well-made and safe to use, and it’s not too loud. Overall, it’s a solid heater and does exactly what I need. Read more
We wanted a small heater for our bedroom because we didn't want to turn on the heater for the whole house to save energy. So we bought this heater. Upon receiving it, the package felt small and light and I had a doubt whether it is any good. But after plugging it in and turned it on, it surprised at how quick it heated up and the covered the whole room. There are so many features including easy to control, quiet, and advanced safety protections. It also has a cool mode which I haven't needed to use it yet but for sure it will be usefully when summer comes. Great device for the winter. Read more
This heater is compact, powerful, and perfect for indoor use. the output warms the room quickly, and the oscillation spreads heat evenly. The adjustable temperature control is convenient and responsive. It’s quiet, efficient, and ideal for small spaces. Overall, a reliable and effective heater. Recommended for users who are looking for a reliable heater for their bedroom, study or any small to medium space. Read more
It works really well but kind of confusing directions. It has both hot and cold features and runs quietly but never shuts off. It just switches from hot to cold and has eco mode. Takes a little bit of time to get used to but evens out the room temperature well and keeps temperature consistent Read more
Works good so far - not sure how long it will last. The remote broke and the heater makes a noise when turned on for the first 5 mins or so. It’s less than 2 months old. Temp keeping function is on but it goes between a 6-7 degree range of the desired range, up and down, so too cold/too hot back and forth within a 6 degree or so range of the desired temp. Not awful, also not overly pricey m. Unhappy about the remote though - and it doesn’t seem made to last. Read more
This product is absolutely phenomenal! I bought it to heat my downstairs bonus room, which is typically 10° cooler than my mid level. I love this product, because you can set the timer and it runs continuously until it hits your desired temperature. It warmed up my basement perfectly and highly recommend this for smaller spaces.

Bought for a small space that gets very cold. Apparently this will only operate if it is fairly warm. When an attempt is made to use in the colder space, an error code of E3 comes on and it shuts off. When trying to use in a warmer place, it runs just fine. Read more
I really like this little heater. It’s small and lightweight, and I use it in my son’s bedroom to warm up the diaper-changing area. It’s very effective and usually heats the space within about 5 minutes. I noticed some reviews mentioned issues with the remote, but it works perfectly fine for me with no problems at all. The noise level is comparable to other space heaters I own—and actually a bit lower due to its smaller size. Overall, it meets my needs well. It’s a great small heater for a baby’s room. Read more
