Haven’t put the units into service yet, (just arrived today) but have tested on 12V supply.
No surprises, they work, are extremely quiet.
Biggest surprise to me is how these guys follow the order. They provided me with tracking number and I was following.
The surprise was that the day of delivery, I got an email from company telling me the order was due to arrive today AND once delivered, they again sent me an email advising “delivered”.
Way to go guys, service well above and beyond what I have ever experienced. Will definitely buy from you guys again.
