We love this door!  It is excellent build quality.  The directions were straightforward although this is not really an easy install for a novice.  The panels are very heavy and awkward to move around.  The directions don't really explain that you need to get the sliding door into the bathtub before installing the fixed panel but I figured that out before.  The door slides extremely smoothly.  I would say that the only minus is not an issue with this product but that in our configuration, you need to get in to the tub in order to reach the shower control.  Again, not an issue with this door but you may think about getting a double sliding door if this will be an issue for you.  I did look at double sliding units but like the look of this kind of door a lot better so it was worth the concession.
