It depends on whether the seller is reliable or not.
I've gotten both my zhanchi and guhong from amazon and they were fine.
I think what helps is to select your products that are dispatched by amazon themselves. It means that amazon are the ones that are actually handling your products and packaging it rather than the seller.
You seem to misunderstand how Amazon works. Amazon handle and package the vast majority of products sold through the Amazon marketplace, regardless of the reputation of the seller.
The seller sends all of their stock to Amazon's fulfilment centres, and Amazon allows them to use their site as a retail environment. The seller benefits because they don't have to pay for warehouses; Amazon benefit because they can charge for delivery, and guarantee delivery times, etc. because it all comes from one of their hubs. That's why everything you purchase on Amazon arrives in an Amazon box. Some overseas vendors (such as Lightake) sell on the Amazon marketplace in addition to their own storefronts because of the added exposure it gives. They fulfil their own orders.
Amazon themselves don't sell very much - Kindles, Chromebooks, etc.. Pretty much everything else is sold by third parties.
I've said it before and I'll say it again - the only way we can stop this is by reporting the fraudulent sellers. These guys are going to great lengths - packaging YJ/Cyclone cubes in Dayan boxes, and applying the Dayan transfers, in order to sell a cube for a few extra dollars, and make a tiny bit of extra profit. They are capitalising on the Dayan name, so both Amazon and Dayan are well within their rights to prosecute. Which they should.
In the meantime, if you buy a Dayan cube on Amazon and what arrives isn't a Dayan cube, report them to Amazon and leave a scathing review!
