Not Buckslayers fault, but I ordered a set from them, he doesnt send shipping information, and I have trouble with mail carriers delivering mail to the wrong house, or just leaving packages on the porch to blow away in the wind. After a couple weeks of hearing nothing, I reached out to Buckslayer to see if they had shipped, he looked and found tracking info that they had been delivered.
Anyway, I never got to try them out, and like I said, not his fault that my mail carrier sucks, but the way he talked to me in the few back and forth emails, I won't be sending him anymore money.
I also tried TOAD (Terry Built Original Archery Designs) out of texas, he has a lifetime warranty on his strings, but I couldnt get my bow in spec, and they came off relatively quickly. I will say they were the quietest strings I have tried.
I had a set of vapor trails, Ears (nickname) was great to deal with, but they accidentally sent me the incorrect length yoke for my top cam (prime), once I got that figured out I didnt even have to twist a cable they were dead on.
I've got a set of Gas Ghost XV strings on order, I just put on a new set of prime factory (free strings every 2 years) and they have been great so far...
All that to say, you are going to find people that have had issues with just about every string builder out there, and you will find lots of people that love them. You're just going to have to roll the dice...
