Its probably quite heavy with the extra SS.
Some may like the valve on top but I found it very uncomfortable.
It looks like they did something funky where the tube is attached to the head.(May reduce air flow)
Looks like the corners of the vac openning will for sure snag some longer napped carpet.
Solution line going into the manifold isn't centered. I don't know if that will make a problem balancing the flow or not. But it some how doesn't seem right.
There's also a gap at the edge that looks like it'd leak a ton.
