Former Etsy seller
I sold my berets on Etsy from 2011 to 2018 and had over 250 sales and 120 reviews there - all five stars - with many of my customers coming back later to buy another hat.
I've now moved away from Etsy, but the shell of the shop is still there under the same name (https://www.etsy.com/uk/shop/SloweTams) if you would like to check my reviews and sales history - just click on the "sales 262" link on the left part way down the home page, and scroll further down for recent reviews.
I don't have any reviews in my Zibbert shop (yet) because, at present, only people who create an account on Zibbert are able to leave reviews. I've asked them if they would reconsider this and let every customer leave a review.
