Installation should be left to those who are very handy or a professional.  Components are all very heavy duty and we are pleased with the quality of the door. Drawbacks would be the height of the bar, and the bottom and middle seals.  We did not put two and two together and did not realize that anyone 6' and taller will need to duck to enter shower.  Secondly the bottom track needed to keep sliding door sealed negates 'frameless' design.  Third, the seal included for the middle (where the doors overlap) is pointless as it does not seal anything.  Plus if you add it to doors it is ugly.  We are looking for work arounds.  Also naturally you want to have door opposite end of water spout.  By design, it creates a ledge near the water spout since slider door is on the inside.  Nice door and we think we saved money.  It also allowed us to have a 'ledge-less' entry.  Thank you
