I just bought an X-rite 810 densitometer off ebay, and it arrived as described and pictured, but it was missing the large button on top for taking readings. I knew this when I bought it, so I am not upset with the seller in any way, but I thought I might see how much a replacement would be from the manufacturer. I filled out an electronic form off their website asking about it and I got a reply in a couple hours. It wasn't an estimate or price sent from a sales rep, it was a receipt for a replacement shipped at no charge. Now that is customer service, especially for a discontinued product!
