I haven't used the polar meter projector, so I don't know much about it. I use VoguePro at home, and I feel quite satisfied after using it for a while. I mainly use it to watch movies at home. The big screen is really enjoyable and the price is more suitable. Compared with the big screen TV with five or six figures, the price of the projector is more acceptable. During the online class, children use it to attend online classes during the day, and the effect is not bad. And I heard that the projector is more eye-protecting, so it has been used for children until now. Now, when I'm not busy at work, it feels good to go home at night and get together with my family to watch movies that my children like and TV dramas that my parents like. It's much better than lying on the sofa playing with your mobile phone.
