Really unfortunate deal with this guy. When I received the Walrus Mantle it would not power on, only making this weird low clicking sound. I tried mutiple ports from a clean power source and still nothing. I then tried another power supply and still nothing. I reached out to Tinman and all he would do is ask AI what might be wrong and send me the conversation. No real research. I then requested to return for refund and he refused and insisted I broke it. Hard to break something that came dead on arrival. This really sucks and I just he doesn’t do this to all of you. I’ve been on here for over 20 years and have never met someone so lacking in integrity as this guy.
