I bought this for more length than my previous "voice" line thinking I'd be able to improve my signal from using a standard cable. As far as I'm concerned the connection stayed the same as without the telephone wire I was using. I did like that it was firmer so I could direct it where it was needed.
I give this product an 8 simply because I expected more and didn't get more without the great opportunity to replace my current wire with comparable replacement.
PROS: Firmer cable, Length, its from monoprice
CONS: Data cable didn't improve or reduce modem experiance
