Pros
1. They are easy to operate. The most obvious benefit here is that these projectors are equipped with simple technology. It doesn't have complicated parts nor does it have too many cables that's why setting it up is never a hassle. You won't have to worry about figuring out different settings and requirements such as software troubleshooting and others. This also means you will be able to avoid computer-related concerns which could possibly ruin your presentations.
2. They are less expensive to acquire and maintain. Compared with modern LCD projectors, overhead projectors require lesser amount of money to acquire and maintain. Purchasing from the right resources could lead you to about 50 percent savings and so this makes a nice choice if you are tight on budget. Look around and try browsing the available options. You will likely find projectors that have almost the same price as an LCD lamp.
3. Transparencies are available everywhere. Regardless if you are using an inkjet or laser printer, there are transparency films that are perfect for your device. These transparencies can be bought from nearby stores that carry office supplies and they are often available for a cheap price.
Cons
1. The heat. Although projector cases are designed to endure the heat of internal lamps, you as a user may still find it too hot to touch. Moreover, certain parts could even cause burns if you are not too careful. Also, be extra cautious not to place flammable materials beside it during or after use. This is important so you can avoid untoward incidents.
2. The toxins. There's always the tendency for the projector's plastic and metal parts to melt because of its heat level. When this happens, the machine will likely release toxic chemicals which may induce dizziness, skin irritation, and others. In case you suspect that you are are experiencing any of these symptoms after using the machine, then it's always best to contact a professional technician to perform checks and repairs.
