I wanted to like these strings. They are made in Germany, which is a plus. I also like heavier gauge strings. Their customer service is great - I wrote to them because I found the low E string to be playing up and they sent me a replacement with some pyramid beer mats!
I put these on my 52 Telecaster, they sounded ok. They are reserved, but have a certain richness I suppose. Nothing very exciting, but they're decent.
First problem I encountered was with the wound G. I wasn't paying attention when I ordered and definitely didn't want a wound G string set. I hadn't tried one before, so I was interested and tried them on. Initially it seemed not as bad as I was expecting, although of course it doesn't bend the note as much as a non-wound string does.
Here's the thing. They die really quickly and when they die they reveal the shortcomings even more so. They go really really muted and the wound G sounds like it's wrapped in cotton wool. Not a good set for me.
Pros - cheap
Cons - wound G unbalances the set, short life, dull sounding
