Sized wrong.
2008-10-17This case is just a bit too small. As such, the headset sticks out slightly.

Must be me, cause my roommate loves it!
2008-04-19Could NOT get this item to stay on my ear!!! This is a constant problem that is my ear type not the products quality. Gave it to my 78 yr old landlord/roommate and he couldn't be happier. So it's just my luck to have "special" ears! LOL

I should have read the reviews first
2008-02-20This case does NOT carry the headset firmly at all. What's worse is that it can freely swivel around 360 degrees, and often ended up with the open side down, dropping the headset onto the ground. A couple of weeks ago, I took the dogs for a walk, and when I got home it was gone.
If you absolutely must buy this one, I would at least recommend using a drop of superglue to prevent it from swiveling. Even so, it really needs some kind of restraining loop or strap.

Voyager 510holster
2008-01-08The holster works good to a certain level. I have had the holster come off my belt a few times. I have also had the head set come out of it a few times, but not lately. All in all it is good product to keep the headset form getting connected to the phone like it did in my shirt pocket.

Not a useful product
2008-01-03I just got this product. I generally really like the carrying case, because I like to clip it to my sun visor in my car. This case does not hold the headset securely and the clip appears to be on upside down and cockeyed. Logically, it appears to me that the open end of the clip should be pointing down away from the the open end of the case, however, my clip is pointing upward the same direction as the opening of the case and is slightly sideways. Also because the case has such a large opening and is not fitted to the headset, the headset juts out from the case which makes it impossible to clip to my visor and use the visor at the same time. This product is almost completely useless as far as adequately securing the headset and appears to be fairly worthless even as a belt clip due to the position of the clip on the back.

Camera basics: shutter-speed, aperture and ISO
In this article, I’ll introduce you to the basic elements that you can use to control exposure in your shooting. If you have a digital SLR, there will be a way to set all of these controls on your camera, but since they differ between manufacturers and models, you’ll need to refer to your camera’s manual to find out exactly how to change them.
All cameras, whether an ancient film camera, or a more modern digital, work in pretty much the same way. Photographs are taken by letting light fall onto a light-sensitive medium, which records the image. Traditionally, this has been film, but more recently, it tends to be a digital sensor. The more light that falls onto the film or sensor, the lighter the image.
Put simply, a camera consists of a light-tight box that stores a light-sensitive device (either a film or a digital sensor), a lens that magnifies and focuses the image onto that light-sensitive device through a hole in the box (called the aperture) , and a shutter that opens ...
Professional video camera
A Professional video camera (often called a Television camera even though the use has spread) is a high-end device for recording electronic moving images (as opposed to a movie camera, that records the images on film). Originally developed for use in television studios, they are now commonly used for corporate and educational videos, music videos, direct-to-video movies, etc.
There are two types of professional video cameras: High end portable, recording cameras (essentially, high-end camcorders) used for ENG and EFP image acquisition, and studio cameras which lack the recording capability of a camcorder, and are often fixed on studio pedestals. Portable professional cameras are generally much larger than consumer cameras and are designed to be carried on the shoulder.
Technology
It is common for professional cameras to split the incoming light into the three primary colors that humans are able to see, feeding each color into a separate pickup tube (in older cameras) or charge ...
