Final Sale


1. A Stock vs B Stock

B Stock has minor cosmetic imperfections that occur during the manufacturing process. Instead of creating plastic waste, they are sold at a discounted rate. Functionally they are the same as A Stock.

2. Can I put this in an enclosure?

We run our tests in a semi-closed enclosure. It is important for there to be enough airflow as heat does build up over time because of how powerful and fast these machines are. Too hot of an environment can damage to the components. We recommend staying around room temperature.
