Quiet and works well. Remote control is excellent. Very simple to use.

It warms up quickly for the price and is good, but there is still a slight smell when operating after setting the maximum temperature...

I don't know what the difference is from convection, but after using it all day yesterday, it's warm. But the farther away from the machine, the colder it gets. There is a smell when starting up, but it probably comes from the melting of the coating on the heating element. Use it for 1-3 days and it will disappear after a little ventilation. Others said there was noise, but I didn't. The remote control and temperature sensor are a bit inaccurate, but they are covered by cost performance. It's a direct purchase product, so I'm a bit worried about the durability, but I hope it won't break and can be used for several years.
