The Complete Handbook of Overhead Projectors

This is a solid reference book that does what it promises, though I found some sections more useful than others. The troubleshooting chapter is genuinely helpful for our facility, and the buying guide actually gave me real criteria instead of vague advice. My only complaint is that a few brand comparisons felt a bit thin—I wanted more specific model recommendations, not just general positioning. Still, worth having on hand.

Exactly what I needed. I manage a training facility with about 20 overhead projectors, and half the staff had no idea how to operate them or fix basic problems. The maintenance protocols in Chapter 5 alone saved us a service call, and now I use Chapter 8's FAQ to train new employees. Concrete, practical, no fluff. This is the handbook I've been looking for.

Good foundation-building stuff here. I appreciated learning the actual mechanics of how these things work—Chapter 1 is genuinely educational and cleared up some misconceptions I had. That said, I was hoping for more depth on the business side. If you're thinking about getting into overhead projector repair or reselling, Chapter 6 exists but feels rushed compared to the technical chapters. Useful overall, just uneven.

Really impressive work. As an AV technician, I've picked up most of this knowledge through experience, but having it all in one organized place is valuable—and I found legitimate gaps in my own knowledge, especially around cooling system maintenance and the legal/regulatory side touched on in Chapter 7. The glossary is practical, not pedantic. I'm recommending this to our entire team.

I was skeptical that there was enough to say about overhead projectors to fill a handbook, but this proved me wrong. The real-world context in Chapter 1 makes clear why these things still matter, and the selection framework in Chapter 3 saved me from making a bad purchasing decision for our courtroom. Honest, technical, useful. No padding.

The technical chapters are excellent, but I feel like the business opportunity section oversells what's realistic. Chapter 6 talks about reselling and repair services in a way that makes it sound easier than it probably is—no discussion of market saturation or actual profit margins. The handbook is solid as a reference, but don't expect it to be your complete business plan if you're thinking of entering this space.

Exactly what a professional reference should be. I work in corporate training, and I found myself nodding along to almost every specific example because they matched my actual environment and problems. The installation chapter solved a focus issue we'd been living with for months. Not flashy, but dense with useful information.
