I can only comment that this stuff isn't worth a damn;

So what on Amazon is worth buying ?
All too easy to import a container load or trash from a third world country, pay a web designer in India £ 50 to make you a web page that looks like you ar a big well established company, get Amazon to warehouse & distribute your junk then close down as soon as the lot is sold an by preference before your tax is due
The last place I contracted to used to rent out spare warehouse bays to ebay vendors .
All of them very shady characters and most selling counterfeit goods.
Some were even so dodgy we would not pick their product till they had paid the picking & postage & the payment was confirmed.
So amazon is not on my shopping list and this is even before the fact that they record every thing you look at, every thing you buy, your credit card details , your address and sell all of this data to anyone & every one who will stump up the cash and that is before the hackers breaking into their data base trying to steal the said same information.
