Review on 🎥 DBPOWER WiFi Projector Native 1080P, 8500L Full HD Outdoor Movie Projector with 4D Keystone Correction, Zoom, PPT, 300" Portable Mini Video Projector for Smart Phone/Laptop/PC/DVD/TV/PS4 by Alex Panda

I'm not sure why people gave such a high rating or I'm unlucky. While staying at home I bought a used Smart Board/Projector (600i6) for my homeschooling kids. everything is fine until the projector lamp burned out. Based on the smart projector specs (3000 lumens, 2900:1 contrast ratio) I choose the highest model from DBPOWER, it should outperform the SmartBoard projector like a breeze. (8500 lumens with 10000 contrast ratio). The result is not pretty. Brightness/contrast is significantly worse compared to SmartBoard. More like 850 Lu/1000 contrast. Even my flashlights I bought at Costco are brighter than them. Revain has a great returns policy and thank you for that.
