Product review (4 stars): Not the pictured product
If you see the image it shows snug yellow caps with metal chains attaching.  The actual item you receive has an all thin plastic oversized cap that just won't stay on, with plastic holding them on... so it's a flimsy camp system that doesn't actually do its job (stay over when not in use and keep debris free).  Otherwise, waiting to install the unit.  The unit types are always better than the old bottled water stations...
