The first ladder broke within a month. Very small in size. I would not buy it again and it is not worth its money. You can find bigger and better quality ones for the same price.

I bought 3 because I found them on sale. Gradually, they all burned out - they didn't last even 5 months of use. It's a shame because they did the job if you have them close to you, for example, near the computer

3 days after receiving it and with very few hours of use (it was still October), the top bulb started throwing sparks and burned out. The store immediately replaced it for me, but unfortunately, after a few days, the top bulb burned out again in the new heater. Due to the way the switch works (either you turn on the top bulb or both), I can't use only the bottom bulb. It would be very good at heating a room if it worked.
