To be fair on the heaviness point though, people add weight to their mice for wireless ones in the form of batteries, and for gaming ones actual literal weights. The raspberry pi is only 45 grams, so it is at least conceivable that this mouse will be a suitable weight. I do however totally agree that a first-time mouse making company probably won't do a great job of making a mouse.
