These type of feedback usually helps the builder to improve their service when you as a customer pick up the phone and express to them your concerns.
The fact that you may have had a delayed response could be due to the simple fact that you are purchasing from a busy builder/ artist.
Most of the best products in the industries are the ones that are built but its original creator.

I don't understand why a tattoo machine box needs to look corporate.
Although Packaging is a science itself.

Next day shipping could mean that the machine gets posted the next day when it's finally built, not when you place an order.
My 2 cents.
