warranty cards

What’s the freaking use of them if the seller doesn’t put his stamp on it before sending the product? On each review done here and yt it says: includes warranty card (if it includes one ofcours. So what, I got like 7 warranty cards and not once did any seller fill it in and put a stamp on it. I got to pay postage to send it back to china or wherever so they will send it back to me, yea right. Next product review I do on website will get 0 stars just for the warranty card not being stamped and filled in properly.
Or am I missing something?

Good question (I have never read any of those, so was not even aware a vendor must stamp them LOL)

I don’t think I’ve ever filled out a warranty card or registered a product in my life. I wasn’t aware you had to fill out a warranty card to get warranty service later on. It was always my assumption that those cards (or on-line registrations) were just to put your name on a mailing list for their sales department.

What’s point of this card and why does every reviewer put it in his/her review if it contains that freaking warranty card. It’s absolutly of no use. I don’t get a warranty even if I have my receipt but not the frekking warranty card!?

If I remember correctly , I think before this current era , depending upon what country the manufacturer was in , you had to physically fill out the
warranty card and mail it to the required site. Also nowdays you can register the warranty online if that way is provided by the maker. However , I
could be wrong somewhere in my thoughts about this warranty registration process. If I am , it’s unintentional.—Now , whether or not the warranty
registration was/is actually worth doing , depends upon the flashlight makers/sellers stipulations of how and to what degree they would or will honor
the warranty ! So many different places and requirements. These days it’s a Crap Shoot !! What do you guys think ?!
