The wanbo vali 1 pro is a dust vacuum...
The wanbo vali 1 pro is a dust vacuum i don't recommend it,i got hundreds of dust spots/dots on the screen after only 8 days of use and before the wanbo vali 1 pro i had a magcubic hy350 max for months without any issues so don't waist your money here and buy something else because wanbo will just send you a unprofessional video of how to clean it with the guy in the video touching the lcd panel with his bare hands and then offer you refund of 20-30$. I was not buying a new projector to clean it every 8 days
