Product review (5 stars): Pay attention to the flared insert
Works beautifully.  Boat for my boat to replace u line $1300 unit.  Pop riveted a flange.  Cut the opening a little bigger.  Voila!  I see where the flooding issue is.  The unit is supplied with 1/4 inch plastic line with a compression fitting.  A flared insert goes into the water line so the compression sleeve will not crush the tubing. But as might be expected, the flare is too big for the connection.  If you attempt to attach the way it is there is no way to get a good seal.  I sanded the edges of the flare to make sure it slid into the fitting, inserted the insert into the plastic pipe after threading on the nut and the sleeve...the narrow part of the sleeve is closest to the flare of the insert at the end of the water line...maybe a half inch away.....make sure the end of the water line fits and slides inside of the connector at the water valve on the unit.  Now slide the nut down over the water line and tighten it.  No leaks.  No adjustments.  Worked well the first time and made first cubes in about an hour.  I'm sold!
