I doubt there were any to begin with. I hope I'm wrong, but looking at the seller... it has scam written all over it.
- seller has only 7 positive feedbacks in the last year
- seller has been selling anime crap up until these saws got posted
- the last two sales have been "private listings" , so you can see anything about them
It's likely a compromised ebay account. The way this works... the hacker posts a bunch of unbelievably good deals. The buyer pays with paypal thinking they're good to go. The seller then drags their feet shipping the item they don't have. When the buyer inquires about it they get some response about processing time, yadda yadda yadda. The buyer presses more for tracking and the seller eventually puts a plastic trinket in an envelope, whatever the cheapest thing is they can mail and still have tracking information. Seller sends tracking info to buyer, but it takes days... maybe a week or more for the package to get to port where it sits. They wait until the cargo container with all the little items are tossed in is full enough to put on the boat. Meanwhile the buyer has to use some janky tracking that provides a bunch of hard to distinguish chinese. It eventually gets on a slow boat. The slowest boat ever, the one that is powered by a couple 6.5hp predator engines. Weeks and weeks have gone by at this point. The seller just needs enough time to get a bunch of sales and money transferred out of ebay without wracking up too many complaints. They have the tracking information and can claim "we sent the items, they're in transit" for a while. Eventually the ship gets to the coast of CA where it hopefully doesn't spend too long getting unloaded. Then you can probably track the trinket... just a few more days until you get that plastic frog or giraffe maybe. The seller has already got payment, already withdrawn from wherever ebay sent the money. They made some thousands and are onto the next hacked ebay account.
If you're lucky and you get tracking information sooner than later you might be able to determine what kind of package was sent, if its a small envelope or box, and sometimes you might be able to find out the weight. If anything looks slightly off I'd contact ebay/paypal immediately. Ebay's protection is only 30 days, but paypal should have longer coverage. And if paypal has other complaints from the same seller they may just go ahead and refund you right away.
I hope I'm completely wrong and the cost of these Chinese knockoff saws have fallen off a cliff, and you can actually buy them for half or 1/3rd what they've been selling for.
