Comments about Apollo Ventura 4000 Ultra Portable Overhead Projector:
Yes, it's lightweight (and somewhat portable), but this is nowhere near constucted to the quality of other more standard overhead projectors.
The focusing lense fell off twice, and it is best attached with a special screwdriver. More importantly, the rerlecting mirror was very sensitive (and loose). DO NOT TOUCH once set!
I could not get the case to "lock" in place for transport.
These problem might be solved with better instructions (which were scant), and I'm not used to having to call for help on how to use an overhead projector- which I did not have time to do.
2000 lumens is also a bit low to distinguish between dark colored tones. For pure B&W, it's fine.
Great display area, noise is standard and display quality is satifactory.
Unless you must travel via air with this, I suggest a sturdier, larger unit.
Comments about Apollo Ventura 4000 Ultra Portable Overhead Projector:
We bought this product to use for church. The construction is really not good. The lens adjuster has broken and come off several times and the arm itself fell down on the glass. We will not purchase another, from this maker, again.

Although the product was light weight and did not take up too much space the quality of material it is made of are poor,for the price a piece broke when setting it up before I even used it. Also the range of how large you can get the image was poor.
