We're in Production!

by Chloe Madison

Hi Friends,

We have just finished testing and validating the manufacturing process of the PwrTool 500 and are in production as of last week. We’d like to apologize for the delays as we worked through bugs in the process. This included making some final changes to the hardware that will improve your user experience and overall safety.

Unfortunately this pushes us back to July as our tentative ship date, but we have pre-production models we’re very happy with and the inventory is paid for. Just a matter of time at this point.
