I own this - the RCA inputs can be stupidly finicky, but I'm guessing if you have it in an easily accessible location that doesn't get a lot of movement, it'll be fine. Gravity is also not your friend with this switch - the RCA jacks will come loose.
For me, seems like I have to troubleshoot an input almost every time I use it.
If it could figure out a more stable/solid input method, this would be a great device otherwise!
thank you for the info. I appreciate it. I decided to get a second 3 input switch to piggyback, which will give me the 5 total I need.
