I bought this projector and when it arrived, I didn't expect it to be so small compared to another one I had bought a year ago. In fact, I wondered why the price was lower than my previous purchase. Anyway, I kept it because, even though it's small, it works for me. I placed it on a low wall near some stairs to illuminate them well at night. It has a remote control which is very useful, and you can change the intensity, color, etc. I like the cool white color that illuminates more. It worked perfectly all summer, but now at night, the light is yellow. I changed the color several times with the remote control, but the next day it returns to yellow light. I'm not very satisfied because it's not the result I want. I thought maybe it's because it's winter and the intensity and duration of sunlight are lower. However, there were some beautiful sunny days that didn't produce any result with the color of the projector's light always remaining yellow. I will wait for the next summer to see if there will be any changes and if it will be the white light I want again. Either way, it's a nice gadget
