Good luck to all of you who are using 3rd party grips or batteries. From your testimonials, it sound like they work well and none of you have experienced any problems, and that's a good thing. Prior to purchasing my Nikon grip, I researched all of the available 3rd party grips, because I felt that the Nikon grip is just overpriced. The 2 primary reasons that I decided on the Nikon grip were because of possible electronic issues and fear that I'd void the warranty of my D7000. I know that many companies have a policy that states that use of 3rd party accessories is unauthorized and will void the warranty of the original product. They always imply that there is a chance that the 3rd party accessory might create some sort of electronic or mechanical malfunction and zap or damage the original product, be it a Nikon camera, a cell phone or even your family car. In some cases this warning might be valid, but I've always assumed that it's just a way that the manufacturer of the original product encourages the consumer to not buy 3rd party accessories and to buy their own accessories. Basically, they're trying to line their pockets and keep all accessory purchases in house. But, it's a fear tactic that does hold some logic. One can't totally ignore the notion that the use of "Inferior" 3rd party accessories might cause malfunctions. So, my point is that if you do use a 3rd party grip or any other accessory, such as a flash or even a battery, and you happen to have a mechanical or electrical problem, be careful with your dealings with Nikon. If your camera is still under warranty, they will probably void the warranty. Is my thinking process correct? Is this an issue that needs to be considered before purchasing a 3rd party accessory? Or, do you guys not worry about this matter? . . . Just food for thought . . .
