I completely forgot I had ordered this, and just came on Tindie to check on another order and saw this one in my order history and realized... I never received it.
To be fair, we were at the peak of COVID-19, so who knows if it even shipped, but I do know I never received it, shame on the seller for not using a trackable shipping method, USPS delivery confirmation is cheap.... and shame on me for not following up sooner... oh well, live and learn, chalked up as a loss.

John:
We offer both trackable and untrackable shipping options. The untrackable shipping option is a bit cheaper, and that's the one you apparently selected.
However, please contact us (here via Tindie or by email) with your order number, and we can probably find a replacement unit to ship to you.
