How do item ratings work?

Viewing all reviews for an item is beta feature, and some shoppers have early access. If you have access, you can tap the item for more details, where you'll see Ratings & Reviews. Tap the number of reviews to view the All Reviews page. There you can sort the reviews by several different options, including newest, oldest, highest, and lowest ratings.

All shoppers can see the average rating of every item that has received at least 5 ratings. Rating your items is very important because this helps other shoppers make an informed decision before deciding to purchase the item themselves. Items with consistently low ratings will be flagged and may no longer be scheduled on the platform.
Why did I receive an email to rate an item, but I haven't received my item yet? 
Occasionally, items take longer to arrive than expected. We send out rating reminders after the Estimated Delivery date even if the item hasn't been scanned "delivered" yet, because sometimes carriers don't scan a package at delivery for various reasons. This is so you have a chance to rate every item you buy on Tophatter, no matter what.
Can I rate an item and then update my rating later if something changes?
We don't offer the option to change or edit a rating that you have left for an item. Because of this, we recommend waiting until you have received, inspected, and tried the item before deciding on an appropriate rating.
