Product review (2 stars): is NOT 1/8" like described.
I have yet to actually try it out but it seems to be build decently for the price. My biggest issue is that these are NOT 1/8" inlet/outlet. They are 1/4" so I have to go out an buy an adapter to use it. Add that to the bad shipping I received.  Two stars is the best I'll do for now, since it was NOT the size it claimed an had terrible shipping time.  Maybe I'll give more after I use it, maybe not.
