The coasters do a good job, they protect my glass table, they look good so far only the holder looks a little very low cost of which would be very Verbesserunswürdig indeed. The coasters are themselves so that they bring to the bottom Schaumgummiert a safe cushion between themselves and the table, there are 6 pieces ever an advantage because many partially only 4 pieces offer (Kopfschüttel) under 6 pieces I would never buy because you normally also 6 glasses has. Priced they are fully OK
