I purchased two sets of these coasters because I absolutely love common fibers- I have used their wallets exclusively for years and their customer service and quality of product has been top notch. Since I love the look of carbon fiber and am a big fan of the company I went all in on these coasters when I needed a set for my new home. I've been using them for a little over a year, and I feel I can very accurately state the pros and cons for anyone on the fence:
- Looks beautiful. Seriously, they are nice to look at.
-Drinks don't slide on them (they stick, see below).
-The base/holder is terrible. You will need to use both hands and take your time to actually get them in the slots. I feel like a surgeon with how obnoxiously precise I have to be to put these way. Even then, they won't stand up straight- they will lean to the front or back.
-Super flimsy. Seriously, I expected these to be thick and they are in fact paper thin.
-Drinks stick to them. As a glass sweats, the moisture will cause it to stick to this coaster. Then when you go to pick up your glass you will pick up the glass and the coaster attached to it, then hear a thud as it falls off onto the table or floor, since the things are so light you won't even notice it's there until you see it or it falls off. Seriously- this happens every time.
Bottom Line: If you really care about appearances and love the look, go for it- but be warned that these don't fill the basic needs of what a coaster should do.
