Has anyone heard of these or tried them i was thinking of getting neck and bridge pups there cheap any info would be good.

I've heard of them!

I don't suppose it would be much of a surprise to anyone if I said they're really good!

There's quite a few user reviews at HC :-

If you want any specific advise re' what pickup would sound best for your guitar / music, just shout!
Just ordered a Hot Slag bridge pup (Love that name),shame i didnt know about the discount see what its like when i stick it in.
