wow ... you must specialise in sketchy sellers. Literally in decades I've had only 2 or three iffy experiences.
Yeah, don't get me started....the worst of the worst was this total nutbag who I bought some color inkjet cartridges from.
This was b4 I realized to NEVER buy anything from anyone who has generic pictures of what they are selling rather than a supposed real photograph (with preferably multiple views and high enough resolution to actually see whatever it is). The cartridges were supposed to be new genuine cartridges pictured as brand new store bought ones like I had been buying for months from other sellers, which come sealed and packaged in their own small boxes, and came from canon's (the manufacturer) website.
What I got instead was a box of "naked" cartridges, none sealed, none in boxes, all wrapped in a big bubblewrap ball, almost like they were thrown together in a couple handfuls with no rhyme or reason by a mentally ill bizarro, and instead of being "real" cartridges they were all stamped with some kind of NOT FOR SALE - PROMO warnings, and half of them were all dried out & unusable.
I already had some bad experiences with a-hole sellers who if you dared to leave them bad feedback and tell it like it is they then leave you some sort of nonsensical negative feedback in retaliation saying things like buyer didn't pay or whatever (back then sellers could leave feedback for buyers) so I figured I would just basically writeoff the $50 and throw them out, not worth the hassle in having someone possibly insane mad at me looking to take vengeance.
But this a-hole then contacted me after a week or two and told me to leave him positive feedback and that he wouldn't leave me feedback until I had done so. The guy definitely seemed "off" but me being me decided to just tell him that I did not leave him feedback because if I did it would be negative, and told him why, told him if selling dried out as-is promotional giveaway cartridges to be honest about it & that way people know what they are getting into & could decide to take a chance on them working or not, but I was over it and not looking to ruin his "perfect" 100% feedback rating.
What followed next was a storm of profanity and threats from this lunatic. The jerk EVEN CALLED MY HOUSE MULTIPLE TIMES (I was not home at the time and he did not leave me msgs from what I recall but I 4get 4sure). He continued to message me through ebay though and threatened me with hellfire if I were to ruin his 100% rating.
I told him to leave me alone and if he persisted in contacting me I would report him to both the police and ebay as well. And that I would not be leaving him neg feedback, not to worry, I wanted nothing more to do with him.
Then on the last day of when feedback for the transaction was allowed, he actually left me a ranting negative feedback saying that I lie, make threats, don't pay, make sure to cancel any bids I place etc etc.
Not saying that is a seller typical of fleabay or would happen if I bought a used meter there, but just relaying a pretty unforgettable negative ebay experience. The others that were negative were more like getting stuff in nowhere near the condition they were claimed to be. I generally avoid ebay anymore but buy a few things there on occasion but only from sellers I trust, have used b4, have good feedback comments, etc. I sold a ton of stuff on ebay btw and have had similar experiences with crazy buyers btw (some even outright thieves). I also used to sell things on Amazon and learned the hassle ratio in general, whether buying or selling, is a lot lower on Amazon, for some reason not as many crazies as on ebay...
