About a decade ago I had a Fitbit and wearing it caused my wrist to break out in a rash. I sent a picture of said wrist to Customer Support and they gave me a full refund on it.
Now, I've not had a watch cause me to break out like that since and I've also never owned any of the other brands on this list... Now you got me wondering.
I cancelled Prime over a year ago and for some reason I still get "Prime" delivery. I don't get the games, movies, or Twitch stuff but if I order something it shows up faster than when my partner does.
So, I don't hate that about Amazon... Everything else keeps me from ordering there unless there's no other options.
