I bought a Canon camera battery grip for my Canon 7D DSLR. Normally I buy these kinds of things directly from amazon or other notable sellers to avoid getting scammed, but they were sold out and I had a trip coming up. So I order from what looked like a reputable 3rd-party prime seller. The grip I ordered is the kind that adds, grip, more batteries and additional buttons to your camera, so you can take vertical shots more easily. It was something around $200.<p>It arrived, and felt like a legit piece of hardware... but after playing with it for a bit. I noticed three things, the blue paint color indicating button functions was slightly different than the ones on my camera, and the patterning on the rubber grips was slightly different than what was on the camera, and the device, although super good quality (that's why I didn't even notice initially) was made of a very tough, heavy plastic, and not the magnesium of the camera body. The box also looked spot on like canon gear. I was faintly suspicious, and started investigating and did a bunch of online searching about things to spot, the proper build materials etc. If I wasn't so picky I think I would have just accepted it. It was indeed a great piece of hardware. It turns out that this was indeed a knock off. A very good one. I ended up informing amazon. They told me they didn't want it back, and sent me a new, legit one. I ended up selling the fake one on ebay, informing the buyers that it wasn't a legit grip, but a very good quality knock off and I made like $100.<p>When the new legitimate Canon grip arrived, it had the same grip material, same paint, made of magnesium.<p>So all-in-all I ended up with a legit Canon battery grip for half the price.
