Everything went well. I picked up the package from the store so I could install the "electronic viewfinder Yale DDV 5800" over the weekend. I'm unhappy with the viewfinder and I wanted to return it, when I had a shock, you can't return something picked up from the store. I'll be interested if it's legal. Anyway, if I can't return it, I won't buy anything from Evomag.
