Renpho Fitness Smart Scale SE - Measures stuff like bodyfat %, BMI, etc., they have an app that keeps track of your progress and it's EASILY resellable on Facebook/eBay
Had a legit problem with a scale of theirs, noticed they have a really exploitable warranty process. Shared it with some friends, they tried it and it worked.
Proof:
I don't expect this to work for a long time since it isn't a very big company. If you did it and it worked, please PM me with a pic so I can add it to this thread. If it didn't please PM me with screenshots and I'll take this thread down.
Keep in mind that I could rape the fuck out of them and resell everything and make some good money, but instead of doing that I shared it here, with you guys, for free. Don't get me wrong; I'm not asking for likes, nor am I gonna say shit like "leechers will be reported hurr durr" indirectly begging for likes, all I'm asking is typing something better than "ty" to atleast show some appreciation.
