I'm absolutely thrilled with this portable heater! This little powerhouse has been a lifesaver during the recent cold snaps. Don't let its compact size fool you; it really packs a punch! I use it in my workshop, which is about 200 square feet, and it warms the space up quickly and efficiently. I love that it offers two heat settings (750W and 1500W) so I can customize the warmth depending on how chilly it is.What impressed me most is how quiet it is. I've had other space heaters that sound like a jet engine, making it hard to concentrate. The JNDRO heater is whisper-quiet, allowing me to work without any distracting noise. The adjustable thermostat is another great feature. I can set it to my preferred temperature, and the heater cycles on and off to maintain a consistent and comfortable warmth. No more fluctuating temperatures!The size is perfect for my needs. It's small enough to sit discreetly on my desk, and it's light enough to easily move from room to room. I also appreciate the safety features, like the automatic overheat protection and tip-over shutoff. It gives me peace of mind knowing it's safe to use.Overall, I couldn't be happier with my JNDRO Portable Electric Space Heater. It's efficient, quiet, and provides excellent warmth. If you're looking for a small but powerful space heater for a room up to 200 square feet, I highly recommend giving this one a try. It's definitely made a big difference in my comfort level this winter!
