What People Say

Stuff USA provides us with a one-stop solution, from planning to manufacture. The circuit, software, and mechanical design were all done by Stuff. Prototyping can be done with 3D printers to molds. It’s really fast!

Stuff USA helps us when our manpower is insufficient. We can get a good start when developing projects. Stuff can get it all together for mass production. They have many skilled engineers in-house.

Since our product was a newly developed one, we had a lot of uncertainty. We asked Stuff and they got back to us right away and proposed solutions to each of our questions. We were able to make the necessary prototype in a short time frame, in time for a presentation.

Stuff USA can handle everything from one piece to mass production. A true one stop shop! It is also great to be able to depend on them with development. The price is affordable and flexible. In addition, the receptionist responds politely as well.
