Input:
User Review: We have had the product for 12 months now.  We have taken almost 3,000 pictures with the product, and deleted 2,000 of those pictures.  This camera just NEVER gets the picture you want.  When you press the button, it can take anywhere from 2 to 5 seconds for it to take a picture.  The absolutely bare minimum time is 2, and is almost never met.  The camera is designed to eat batteries for breakfast, lunch, and dinner.  We had to buy a rechargeable alkaline system in order to avoid going to the poor-house.
The smart engineers who designed this camera noticed that it eats batteries too quickly.  Their solution was to turn off the camera if you let your finger slip from the "shoot" button for only a moment.  If you are fortunate to be saving batteries in this way, it takes only TEN SECONDS for the camera to warm up and be ready to take an action-packed shot.  This TEN SECOND delay is incurred when you press the "take picture button".  The screen often goes blank right before you press this button.
We have used this camera to miss literally thousands of wonderful shots of our twin boys. ...
If you like to miss photographs, if you like to get pictures of people looking the other way, or with their eyes shut, or with their body turned entirely away from the camera, there is no better camera on the market for this purpose.
We're buying another camera.  This one is just too useless.
