Product works and is an official Nintendo product which is important. It's nice to have a newer model with a built-in motion sensor. We only had three and that rounded them out to a good four consoles. However, it was shipped from China and, as is usual with orders from that region, it did NOT come with any instructions. Had to search the web to figure out how to sync this to our Wii Resort system because it just wasn't working. In general, I think that the source an item is being shipped fromโฆ
