Summary: I am using various projectors as my main TV for about a decade now, and this was by far the best projector I had. Fantastic optics, extremely bright, clear, sharp image. Unfortunately it lasted only about 12 hours of projection time.
Summary: The information in this web page is incorrect. This product is not HD33, The product name and specifications in this web page is HD33 but when I bought it they sent me Model TW615-3D which low qualities spec and cheaper. Don't place the order to this product if you want to buy HD33.
Summary: I purchased this item from this company(Which I already returned)thinking it was the HD33...They had the right picture then, however they send me a $699 projector instead, asked them to send the right one they claimed out of stock.
Summary: This seems to be an error. The Model number displays TW615-3D as the projector, but the title says HD33. These are two different projectors. One is 1080p, but the TW615 is only a 720p projector. FYI for everyone.
