I wasn't looking for them for a month or so but now that I'm back to ordering a lot, I was watching for them and didn't see any.
Then the link between mystery items and people having their Vine membership cancelled came up over in r/amazonvine and I wondered if Amazon had spotted and stopped the scam.
Of course, I may just be missing mystery items but haven't noted any chatter about them here for a while.
I just received a cell phone tether that clips my phone to my belt (or purse). I like the item and have a particular need for it.
To review I went to put it on my old phone (which my grandson plays with when here) so I could take a picture of it using my current phone. When I took the case off the old phone, I noted the back was lifted and can see that the battery has swollen.
Had I not had a reason to look closely at 'his' phone I would have handed it to him next time he's here and, since the battery is dead, plugged it into a charger.
Definitely a fire hazard and near disaster avoided.
