Query: Sent wrong item

Normally I wouldn't have rated this at all, because I returned the item for a refund. But the seller, sportswarehouse, keeps sending me e-mail asking me why I haven't reviewed the purchase. So here goes.This is billed as a refractometer for measuring sugar content in beer or wine. What I received was a refractometer for measuring salinity. There was no included conversion chart or anything to compensate.So, why 1 star? Not for the item, but for the seller, because they very clearly described this item as being for homebrew use and saying that it measured in deg Brix. I bought this knowing that many other people also got the wrong type of refractometer, which means that this seller either is completely incompetent, or they just don't care.
