I demand a vise that looks like the picture in the advertisement, not like one of the sorry looking examples that show up on calls for help posted in machinist forums. If you search suppliers for pictures of this vise, they don't look like the above. They have nice, smooth, flat rails that look fine for a parallel. By the way, I have a vise that has this problem. I'm not complaining, however, since it was thrown in with a drill press which came from Craigslist, and it was well worth the price with or without the stupid vise. I would post a picture from one of the advertisers, but most of them are disabled from copying or watermarked, so anyone interested can search them up. I suppose that you cannot complain if the item does not match the picture. I bought and oxygen and acetylene regulator on Ebay, and only received the oxygen regulator. When I complained to the seller, I was told, "you only get what is in the picture, not what is in the description." Plus, I got nailed with negative feedback. All that is asked is to receive the item and not be intentionally deceived.
