Bought two of these and one came DOA. RMA'd with monoprice and was able to resolve the issue. The DOA had parts rattling around inside so I didn't even bother opening it. 4/5 stars as this wasn't a shipping issue and should have been caught somewhere in QC...
Extremely easy to set up and use. Haven't had them in use for long so I cannot attest to their longevity but the construction feels solid. I will say that the jacks feel almost too tight. Shouldn't be an issue though as I don't plan on plugging cables in and out constantly.
They both did come with rack mounting clips so that was a plus.
Overall would recommend even with the slight issue I had.
