The real lesson here isn't about the tool, it's that you bought it before you had a project that needed it. People do this all the time with tools. They see a guy on YouTube make a cabinet and think the tool makes the skill. Better move is to buy the cheap version or borrow one first, and only upgrade once you've actually worn it out. A biscuit joiner is also kind of a one-trick tool. Pocket screws or a dowel jig will do most of the same jobs for less, so now you got a $280 paperweight taking up shelf space.
