When CIRQL customers make a swap and return toys to us, they can also leave a review of their experience with the toys. Customer reviews are scored from 1 to 5 full stars (no half star ratings).
A Bayesian average is used to calculate the overall customer review score. This means that toys with very few reviews still have a more representative overall score.
This customer feedback is extremely important in helping other customers decide what to borrow from CIRQL, but also informs CIRQL's decisions when deciding which toys to offer in its library.
