I just bought them for they was cheap and wanted to test coated strings.
I was suprised how good they was.
The pros is they are cheap and they are coated. They also sounds good. They stay in tune for a long time.
The con is they still not they high quality sound from them you can get from Daddario. Other then that I have not find any wrong with them.
If you want cheap coated strings I think they are just fine.
You can buy many of them and still they are cheaper then coated brands. If you never played with coated strings they might feel sticky in the start, but it goes over fast. Also if you use string cleaner and lube, you can do it on this to and they will hold the coat and they dont get sticky. You will change the strings long before the coat is gone. So they will hold the sound very long.
