Comments about Clover Data Products® R3027 Two-Spool Universal Calculator Ribbon (C-Wind); Black and Red:
Tried the Porelon brand previously and it would be too light to read by the end of the day. Tried this Dataproducts brand off a review on another site and it has now been working continuosly for a week without lightening! Yay!
Bottom Line Yes, I would recommend this to a friend
