Beware of counterfeits 1

I bought this battery from E-TECH. She was announced as an official and had a price close to the price in stores.
Unfortunately, at the reception, I quickly realized that it was a copy. The battery was wider than original and not even returned to the camera.

I requested a full refund of the product and the cost of return that I quickly got but I was very disappointed to receive a counterfeit when I just wanted an original. I do not know if it was a mistake E-TECH or deliberate on their part but I can only advise to be very careful when buying (there there's a good guide to identify false bateries on eBay look for "LP-E6 battery counterfeiting" on google to find it)
