Is THUNDER 04 on Weidian worth your time? Let’s break it down like a real shopper would.

The Good Stuff

Warehouse shipping speed is killer. The seller ships to your agent’s Chinese warehouse in about 1.6 days on average. That’s fast, no messing around. Dispatch takes a bit longer (2.9 days), but still pretty standard for Weidian.
Zero defect records. Out of 298 products, nothing flagged as faulty. That’s clean.
5-star rating and solid reviews. The 4 reviews are all positive, though that’s a tiny sample size. People rave about the Check Collar Polo Shirt—calling it high quality and a perfect fit. The Signature Hoodie gets props for print quality, even if it’s a lint magnet (more on that below). One buyer loved the Equestrian Knight Hoodie, mentioning it’s a high-end jacket with great fit and top-tier materials.
Top saved items include the 8XL (oversized? no clue), Check Swim Shorts, and that Equestrian Knight Hoodie—so these seem to be the crowd favorites.

The Not-So-Good

Sizing runs small. The Signature Hoodie review straight-up says order a size up if you like comfortable clothes. That’s a common pain point with Chinese sizing, so don’t assume your usual size will work.
Lint attraction issue. That hoodie picks up lint and looks darker because of it. The reviewer says the retail version does the same, but still—annoying for a premium-priced piece.
Price isn’t low. Multiple reviews mention it’s “expensive” or “not exactly cheap.” So if you’re hunting for budget steals, this isn’t it.
Only 4 total reviews. That’s barely any feedback. The two Check Collar Polo reviews are literally copy-pasted (same text twice), which is a bit sus. Could be a fluke, but keeps you guessing.
No return rate data available, but with zero defect records and fast shipping, that’s likely not a red flag.

Verdict: THUNDER 04 is a solid choice if you’re after high-quality tops (hoodies, polos) that feel premium but come with a higher price tag. Just be ready to size up and deal with some lint on darker fabrics. The warehouse delivery is a breeze, but the low review count means you’re partly flying blind. Worth a shot if the saved items catch your eye—just don’t expect a bargain.
