Summary: We have employees who travel to do software training. This unit replaced a Proxima X350 that our road warriors used for many years. Size & weight are very similar, but the performance is (of course) far superior to the much older unit. Had no problems connecting from a variety of laptops and Tablet PCs via HDMI, and it even scaled very nicely from an MS Surface Pro 3.
Summary: Fantastic projector. Amazing that such a small projector can pack such a bright punch. Image quality is very sharp. Easy to set up. Only one regret: we purchased the BK-4021 carrying case because the projector description did not mention a case (see "What's in the box?"). Well, it DOES COME WITH A CASE. So, save your money and the return shipping fees. Hoping Amazon will see this and correct the product description.
