Very nice unit.  Jets work great under normal pressure condo I'm in.  One thing to note if you have a low shower ceiling is that the top of the unit has no cover... so you see the white plastic pipe, if it isn't high enough.  For a new shower, I would recommend mounting in the corner, as a result.  If an older shower, mount as high as absolutely possible.  I will be buying a bottle of silver paint at the hobby store and painting the pipes, because when I stand 8 feet away, I see them... they should have finished the top enclosed in stainless... real shame.  Not worth returning, and it is very impressive and fully functioning and doesn't feel cheap by any means... I highly recommend, but please be aware of that.  Also, you might need to buy extension hoses to reach into your shower... and be prepared in many installations to have to remove valves and sweat copper fittings on... overall, at $25 per hour for my handyman, spend $175 installing in my situation.
