Review on 🧱 Ravensburger GraviTrax Expansion Multi 27601 by Sean Skinner

Pressing the button will raise the ball stack and another ball will start moving along the lane. This is good for lanes with elements that don't need to be dropped, allowing multiple balls to be on the lane at once. There are 3 stackable lift tubes, so the ball lift height is a little adjustable. You can rotate the output but not the input, giving you a button that's awkward to press. It's a great addition to the set though, it works well, it's reliable and there's little that can replace it. I would buy it again. This adds a lot of flexibility to track construction, and pressing a button is definitely more convenient and faster than manually placing the ball at the top of the track.
