Unfortunately, I had a poor experience with him as well.
I ordered a pair of CA-14 omnis from him on February 8, 2023 and the Ugly Battery Box a couple weeks later. By the 23rd, they had not yet shipped, so I reached out. March 6, I'm told they're "going out this week." March 11 comes by and I request a refund and open a dispute with PayPal. I get a response blaming the weather for the delay in shipping and how this is just a hobby business and all that. Then he asks me if I'll accept $60 back as a refund on the battery box and he'll send out the mics in a couple days. I accept, close the case and within a few days, both items arrived in the mail. So, I got a free battery box out of the deal, nearly a month and a half later.
Another thing I wasn't too impressed by was the lack of packing materials included. Both the mics and battery box were sent in a plain, flat bubble mailer. For what was to be $200 worth of audio recording equipment, I was shocked to see how poorly they'd been packed.
I've yet to really use any of this stuff, actually. Went through the hassle of bringing it with me into the Hollywood Bowl on 04/22, but figured trying to stealth from way in the very back of the Bowl while there was an OTS would just be futile.
