If the replies dry up after one message, keep your expectations low for the first fortnight — otherwise you end up judging it on a bad day. Which models do the camsoda reddit community like the most — seems like a simple question but I keep getting mixed answers depending on where I look.
Skip anything asking for a card number to read messages, because the first week is never representative, though it depends heavily on where you live. For what it's worth, if you keep matching but never talking the answer is usually to widen the distance radius early on rather than report the obvious fakes rather than ignoring them.
