Most reviewers tending to the negative seem not to understand that Etsy is a platform and not an online shop
You will have to choose with care which seller you are buying off, as you will have to on any online platform
If the seller accepts paypal not much can go wrong: if the item deos not arrive or is defective, you can get a refund
What's very nice about Etsy is the wide range of handmade and/or vintage items, as such a wide array is not available elsewhere in such concentrated form AFAIK
