Anyone ever dealt with these people? I bought a Torker from them, on Amazon it says the item has left their facility, on UPS it says a shipping label has been created and the tracker will be updated when the item reaches their facility.
I read a lot of negative reviews (90% positive, 10% negative, but still sketchy) about them. Suddenly I’m not so sure this was a good idea.
Has anyone else ever bought something from them? When the shipping label was created on Saturday, I can understand no action over the weekend, but on Monday I at least expect them to get the unicycle to UPS.
