more accurately late 2019 when we needed to start figuring out how to make them ourselves when we had over 100 customers dead crossfires piling up, we "cracked the code" during covid lockdown.

we may have spoken on the phone yesterday, i had a few conversations similar to your scenario yesterday, if those calls were not from you, give me a call or email rob@needswings.com

btw, we are a real company that actually answers the phone
