I've never seen the need that people have to get all out of shape when a person asks a legit question all they had to say what was said here in posts # 3 & 4 and its all apples.
But some take it that the question incites a questionable validity of the item and their integrity as a seller so they get their backside under their armpit and leave the sand pit maybe they don't know anything themselves and the rebuke was a cover up.
Anyway you have your answer here from those that have the knowledge and given in a polite and respectful manner as is always the case on this site, just pass on that person its obvious they are inadequate behind their fly!
