Overall it's a fun accessory to have for my family to use. But there are a few things that I had to do to make it feel safe and to my liking. The post that mounts onto the WW uses a plastic sleeve that helps secure the seat post. Because of this, you'll get some slippage of the height. To resolve this, go to a bike store and get a carbon fiber grip that used for seatposts. Or a cheap method would be to get some bike grease and sand and line it within the scooter mounting post. The overall height is too low, even when it's at the max. And because of the suspension in the seatpost, the overall height will go even lower. To resolve this, I purchased an extended seatpost (450mm). As for the seat, I don't feel too confident of the overall design. Since the seat folds down toward the front of the scooter, the front end is secured by a hinge and the back by just a small hook. I got rid of the seat and replaced it with a proper bike seat. And because of the placement of the seat on the scooter, you'll notice that most of your body weight is towards the back. To compensate, you'll want to move slightly forward. So using just 1 of the 3 pieces, I give it a 2.5 stars since I had to invest more into it. YMMY
