I bought one and received another ... Different that I bought...
There was a default with the optic. The conversation with the seller went correct and at a point we decided to send the optic back to the seller and return the payed som. Here is where it went wrong. I had to pay an extra 29€ at the post office to return the item. The seller reacted as "Not my problem. Aliexpress must deal with this". The dispute was deleted without notice and no money was returned.
