I've been using WISH for over a year. Yes it take a while to get your items and I've had a few problems, but for inexpensive purchases its been fine. Ive purchased a swim suit from them- it appeared to be the exact same as the catalog I had so I purchased it. Asian clothing sizes are much smaller than US, so I normally wear a XL or a 1X, everyone says to buy it 2 to 3 sizes larger I ordered a 3X.. well I received the suit. same as the catalog, only the bottoms were a bikini (LOL) and although they said 3X they were more like a 5X (BIG LOL), The top fit, but was a bit tight. Ive purchased dog sweaters and T shirts, and they were true to size. Dog Harnesses and leash sets.. Perfect. beautiful costume jewelry. LOTS of those snap charms, necklaces, bracelets- high quality and very well made. NO, seconds all stones were there. Some shoe racks, dog toys- had a strange odor, but my dogs have chewed up everything from PetSmart, but these have lasted.
The only problem I've had was last year on black Friday, I ordered a "romba" style vacuum.. the highest cost purchase I'd made and it was sent to the wrong address, somewhere in Texas. All reviews said the same thing, Wish refunded my money. Unless the item is tracked, Wish asks you if you received the item, I assume that's how the seller gets paid. If the item is later than the estimate, Wish will give you a refund if you ask for it. You can also track your items.
Try it for a few lower cost items.. that's what I did.. I'm pleased.
