We purchased this glass panel when we renovated our guest bath two years ago and will be buying the same one again this month as we are renovating our master bath. We initially made the purchase through Wayfair because this was the cheapest option for this particular panel. We had priced the same panel through a shower and glass installer (5 times the price of Wayfair) and several online retailers which ranged in price but were all higher. The install was easy and quick (our friend who was helping with our renovation installed it in less than an hour). 
I am still happy with the purchase and find it easy to clean which was the primary reason I wanted a frameless fixed panel in the first place.
