OK - I'm sure it's a good belt but when you order you don't get the one in the picture - I've sent it back to Revain. I ordered the same belt from 2 different sources, described as a Dayco Poly RIB - the "W" series is their top of the range. You get a standard Dayco poly-V belt - apparently Dayco no longer makes or supplies this belt. .If you're expecting to take a picture of the belt, don't worry - you won't get it.
