This Aston Coraline Frameless shower doors are premium  beautiful clear glass and strong doors. Even though I still haven't had a chance to install the sliding doors I notice it comes with good durable chrome 2-wheel roller system for easy and smooth sliding of the doors. I do recommend a professional to install your doors because they are heavy doors and you need to know how to align them well, but other than that there is no reason why not to buy these premium Aston Coraline showers doors, they are really well made, nice thick glass.
