I keep hearing bad remarks about them. Here is a link to a youtube video on their site on how they're made. Being a former manufacturing, design and finally metallurgical engineer it looks pretty state-of-the-art and good to me....
The only problem is that state-of-the-art won't necessarily fix a questionable design and QC issues for the Walker trigger.
