What the address actually says
Oopbuy uses platform in the path — /product/taobao/, which only Oopbuy uses. That is one of thirteen distinct URL families across the forty agents in the converter above, and the reason a spreadsheet built for one agent does not open in another without help.
The gap, stated plainly
We hold three verified figures for Oopbuy: a 4.2 Trustpilot score, 797 reviews behind it, and a published claim of no service fee. We do not hold a fourth. Its free-storage window is not stated on any page we could reach, and the 90 days that appears next to it in our comparison table carries an asterisk for exactly that reason.
Every other agent comparison we checked prints a storage number for Oopbuy without a source. It may well be right. We are not going to copy it, because copying an unsourced number is how an unsourced number becomes a fact.
The URL format only Oopbuy uses
Most agents put the platform in a query parameter. Oopbuy puts it in the path: /product/taobao/, /product/weidian/, /product/1688/, followed by the ID.
This is tidier to read and slightly worse to hand-edit, because the platform and the ID are separated by a slash rather than sitting in one parameter run — so a careless copy takes the ID and leaves the platform behind. It is one of thirteen distinct URL families in the converter, and the reason the converter exists at all.
What 797 reviews supports
Oopbuy and CNFans share a 4.2. CNFans reached it on 13,300 reviews; Oopbuy on 797. Both are real numbers and they are not the same claim.
Seven hundred is enough to rule out a catastrophe and not enough to rule out a bad quarter. The sensible reading is that Oopbuy is probably fine and has not been tested at the volume the top of the table has. Order small the first time, which is advice that costs nothing and is worth taking with any agent you have not used.
The short checklist
Because one of Oopbuy's four numbers is missing, the sensible approach is to treat this as a trial rather than a commitment.
Order one item. Watch how long the QC photographs take and how many angles you get without asking. Ask support, in writing, how many days of free storage you have. That single question answers the thing we could not, and it costs you a message.
If the answer comes back, send it over — we will publish it and credit the source. A reader with a screenshot beats a competitor with a guess.
