I had a very easy time navigating the web page and using filters to find what I was looking for. The varied selection was nice to see and pricing is clear and fair.

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc

Easy picking, fast checkout, secure shipping. Cana't ask for anything more than efficiency and a good price.
