To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Be advised, while the two wheel kit is well made, this version does not work with the Burley Tail Wagon. The plastic bumpers prohibit full insertion of the rails. Look for the other listing on Amazon that does not have the large plastic front bumpers if you have the Tail Wagon.
