I have the heater in my workspace
It has been working non-stop for 3 winters from October to around March
One bulb at the bottom has burned out but the others continue!

I can't say it has a high intensity but for its size, it is quite good

The fan makes a very annoying noise.
I do not recommend it.
Update
Turns out, the annoying sound was because the wheels were not tightened properly. Other than that, it works great, heats up quickly, and has not had any issues

It does its job, but it smells a little and it doesn't have a button to turn off the fan. So when you turn on the 3 front lights (which only turn on all together), the fan also turns on simultaneously. So you have 3 options.. either the small one on top, or the 3 lights + fan, or all together.

I bought it about a month ago...it turns my room into an oven...if you only turn on the 3 front bulbs, it warms you up from a distance of two meters...I turn it on for 10 minutes at full power and then I only turn on the top bulb for temperature maintenance, which is only 600W...in addition, it has a pleasant lighting without bothering like halogen lamps...I come after a year to tell you that all the bulbs are still functioning and it has exactly the same performance...I am very satisfied.

I got it for my son's room but I will throw it away. At first, when we turned it on, it smelled very strong. I thought it was because it was new, that's why it had such a strong smell. It's been 4 months and it still smells very strong, so much so that it could make us sick. The quality is very poor, very cheaply made. I will throw it away and buy one from a different company. It definitely is not worth its money

The heater is very good and I was satisfied with its performance. It presented a problem with the switch, but the store I purchased it from was excellent in its service.

It is definitely value for money, especially for small spaces like 16-25 square meters. I don't have an opinion on consumption yet.
I couldn't stabilize the wheels, hence the 3 stars.

I would give it 5 stars, but if it worked properly as the fan claims... in essence, it does nothing... other than that, it does its job for a room. As for the electricity company, I measured it with the meter (while a refrigerator and a freezer were running) and it consumed 2.2 KWH per hour with all the lights on

For a small room, it is sufficient (with all the bulbs turned on), therefore also the corresponding consumption. I got it on sale for €23. I made modifications to the switches so that I can turn on either 1 or 2 or 3 bulbs separately, depending on what I want. The factory options were unacceptable (3 in front together + 1 on top). For me, it's value for money.
