With some preparation this unit is easy to use. The instructions are challenging to read so be ready to hit the internet to clear up confusion. Vevor does have a website and I did not need to contact them. I ran this for an hour on an uninsulated 500sq ft garage on a windy day at -1C and it got the temp up 5C. That is impressive, I expect when I insulate this heater will be enough to warm it. Mounting is difficult as you need to consider where to exhaust, the intake/exhaust ports come out the bottom. I probably should have bought the mode model that is all separate components versus all-in-one. A muffler is provided but I don't see the point of it, the noise level outside is that of a dryer running. This model has Bluetooth but you need to download an app to get it to work and I haven't tried it, again the instructions aren't the best. The remote works easy enough but the range is only about 30 feet at best, I wish it went 100'. While running the unit makes a 'tick' noise (watch my video) from the fuel pump, you may or may not be driven insane by that. Another thing to consider is the power supply. You must supply 12V at 15A minumum to start and warm the glow plug, once running it'll draw about 2A full speed. Overall these are neat units to heat a space, the air is dry unlike propane heaters which will make your space all wet. For the price it is an excellent purchase!
