Fantastic heat output

COctober 29, 2025

I've had quite a few heaters I regularly use, this thing is awesome in comparison! I'm impressed how toasty even the low setting is, and yet is not hot to the touch & I have no worries of my feet tapping against it even without socks. No noise, works amazing. The only negative so far: initially there was a slight chemical/wood smell when turned on (not present when unboxed), like off gassing of the glue in partical board - hopefully it goes away, but it isn't too horrible just reminds me a bit of a cabin Read more

Warm, cozy comfort that makes chilly days enjoyable!

CustomerDecember 22, 2025

I wasn’t sure what to expect with this leg, warmer and blanket heater, but it has absolutely exceeded my expectations! The soft blanket material feels super plush and cozy, so it’s like getting wrapped in a warm hug every time I use it. I’ve been using it under my desk while I work and also while relaxing on the couch, and it really makes such a difference. It’s quiet, easy to set up, and feel sturdy and well-made. Overall, this has become one of my favorite cold weather essentials. If you want a simple, soothing way to keep your legs and feet warm without blasting a heater or piling on blankets. Read more

Wonderful item. Highly recommended for those that need extra heat in the office.

Michael M.October 30, 2025

Wonderful item! I purchased one for myself and my boss. I don't like having the heaters that blow the air, due to them being a bit nosey at times. This foldable heater doesn't make any noise at all. It's easy to move around and also easy to store when not needed. I like the adjustable temperatures and also the timer. The timer comes in handy during busy days if you are a forgetful person. The addition of the blanket also helps keep the heat where you want it. I didn't use the blanket, due to the fact that I had a metal desk and enjoyed having the heat rise up to the desk to help keep my hands warm. Read more

Nice as an Office Heater - Warm and Quiet

kayloreNovember 29, 2025

I bought this for the office. It is nice, quiet, and warms. The blanket helps trap the heat, although a larger throw would be nice. Super easy to install (it has little feet to provide stability). A big plus is the heat doesn't overwhelm like a traditional heater tends to do. Overall, pleased. Read more

Make's My Work Life So Much More Comfortable

River OaksSeptember 9, 2025

It seems that I always feel cold. I have a space heater. But even on low, I could only handle it for a while, would get too hot and have to turn it off. So, it was always a battle of off/on/off/on. Even though I got one that was supposed to be quite, it was still fairly noisy. I had looked at these under-the-desk heaters, but couldn't get myself to go ahead an purchase one. Finally, I was so tired on feeling like Goldy Locks, too hot or too cold and decided to make the plunge. I am SO HAPPY I did. It doesn't make a sound at all. At the lowest setting, I am just about perfect all day. Occasionally, I do get a bit warm and turn it off, but mostly low is perfect. Unlike some other reviewer, I do not find that I would need a heater under my feet. This works well. I do have a foot cushion, because I am short. So, my feet are off the floor. That could make a difference. I highly recommend it. If you are on the fence, jump over and purchase it. The only improvement suggestions I have would be (1) make the default heat level to be low. (2) It that it would be great to have a remote or for the controller to be able to go on the desk. Having to look under the desk to turn on and make sure the settings are what I want. For those of you like me who are easily chilled, this is only for your legs. It does not help with cold hands. I got a heated desk pad, which has been awesome as well. The combination of the two keep me feeling comfortable during long hours working at my desk. Read more

Small and strong chemical smell

FrankNovember 4, 2023

I recently made the unfortunate decision to purchase this panel heater that boasted about using radiation as its heating function, and it has been nothing short of a nightmare. This review is meant to serve as a cautionary tale for anyone considering a similar purchase, as the drawbacks and disappointments with this heater are too numerous to ignore. The first and most alarming issue with this panel heater is the overwhelming chemical smell it emits when in use. From the moment I turned it on, my room was filled with a noxious odor that made me question the safety of the product. The manufacturer claims that this smell is normal and will dissipate over time, but weeks have passed, and the odor remains as pungent as ever. Breathing in this chemical stench cannot possibly be healthy, and it has left me concerned for my well-being. Even more frustrating is the fact that this heater simply does not get hot enough. I expected a heater with radiation as its heating function to provide a powerful and efficient source of warmth, but it falls miserably short in this regard. It struggles to raise the temperature in even a small room to a comfortable level. I find myself constantly shivering and wrapping myself in blankets just to stay warm. It's utterly disappointing to invest in a heating appliance that fails so miserably at its primary function. The size of this panel heater is another significant letdown. It's far too small to effectively heat a room, and the design is particularly ill-suited for those who want to keep their legs warm while working or relaxing. Unlike other heaters that can be wrapped around the legs, this one simply lacks the coverage needed for adequate warmth. It's a huge inconvenience, especially during the colder months when staying warm should be a top priority. In addition to the chemical smell, inadequate heating, and poor design, the overall build quality of this heater is subpar. It feels flimsy and cheaply made, making me question its durability. The control panel is confusing and unintuitive, adding to the frustration of using this product. Read more
