Everything I Expected
2008-11-18The remote has enhanced our ability to do presentations because of its smooth and reliable button action. Further it gives us the ability to move around our sanctuary during a presentation because of its range. The display is clear and readable and knowing the battery strngth is a big advantage. We would recommend this product to anyone needing a presentation remote with this range.
Top wireless presenter
2008-11-18I make frequent presentations during a month, often times even one presentation a week, so having a practical wireless presenter is very important. The buttons and functions of each buttons are ergonometrically configured on the unit and offer the perfect set of options presenters need; this even has one that "blacks" the screen so you could hold a brief discussion without the distraction of having something on the screen. Furthermore, determining the function of each button is instantaneous...more so than other wireless presenters I have used in the past where you have to determine the functions of the buttons by "trial and error"...not a good thing for a presenter. Ease of use is top for this unit...I wouldn't make a presentation without it.
Coredless Presenter
2008-11-16This is a very functional and useful gadget. I use it for teaching and it is nice to be able to move around the classroom and not be tied to the computer. Some nice features are the laser pointer and the "black screen" button. We tried out the cheaper step down from this model, but that one had an awkward small button for the laser pointer. This model has nice sized buttons that are easy to use and won't make your finger tired or numb. This model also has a built-in timer and a vibrate notification for the timer (I haven't used them though). We actually purchased 3 of them for our department. We had concerns of them interfering with one another, but each unit is specific for it's receiver, so no need to worry about the presenter in the next room changing your slides. Would highly recommend this cordless presenter.

Digital camera batteries
Batteries are vital for all photography and makiing sure that you have a spare set is essential if you intend to take alot of pictures. Print digital also recommend that when deciding upon a digital camera keep in mind what sort of batteries it takes. Does it take rechargeable batteries, are the batteries built and do you have to plug it into the mains, or does the camera only take standard batteries, if so then it can become exspensive if you are a keen photographer and use the camera alot.
There are three types of rechargeable batteries: NiCD, NiMH and Lithium-Ion. Nickel Metal Hydride are the most popular rechargeable batteries at present. They hold more charge than their counter parts NiCD and don't suffer from memory effect. The one small down fall of these batteries is that they will loose a small amount of charge even if they are not being used, so be sure to check the batteries before using them.
When you purchase a new digital camera make sure to ask what type of battery ...
Digital cameras are good for the environment
As we consider the digital camera revolution that has taken place over the last decade, most people think about it in terms of enhanced benefits for consumers. We can take a lot more pictures at much lower cost with digital cameras versus film cameras. We can also more easily manipulate and share those photos since they're all in the digital realm.
But one thing many people don't think about actually deserves mention as potentially the most profound effect of the digital camera revolution: how digital cameras greatly reduce the destructive impact on the environment compared to film cameras.
At first, you might think, "How can that be? My film camera didn't harm the environment!" Even though it wasn't your camera that harmed the environment, your film processing did indeed harm it. Any time you take your pictures to a photo processing center, that film is run through batches of chemicals. These chemicals are environmental hazards, and once they are used to process film, those chem ...
