You are protected by EBay's money back guarantee. You will get exactly what you ordered, exactly how it was advertised, or you are guaranteed your money back by EBay.
All I can advise is that you do your due dilligence reading the details in the listing you are interested in. Read the details, read the description, look at the pictures.
Check the seller out and their feedback. What do you think regarding what other buyers say?
If the item appeals to you, and you are ok with the seller, buy it, bid on it, or make an offer if applicable.
Number of sales may not be high but review what others have said. I've been selling since April, I don't have a long track record, but I like to believe buyers are confident in me based on my stellar feedback and how I present my listings.
Again, you are 100% covered by EBay. If it doesnt come exactly how it was advertised, you'll be able to get your money back 100%. It's called EBay's money back guarantee. Protects buyers, not sellers.
