Okay, thanks for the info. I really like the Wyverns and the first two I bought lasted me well over a month each. I was just kind of thrown off by the last two being messed up, I guess. I am going to order a couple more since the price has really dropped on them and this time I will test them out as soon as I get them so if there is a problem I can do something about it.
My main hold back from rebuilding them is that you are supposed to test them with a meter before using them and I don't have one. I guess I will just have to put my big girl panties on and check into getting one and find a really detailed video on how to rebuild them. But really right now Eric has them priced cheaper than the regular low res atties that I buy at my local vape shop so I still feel like I can toss them.

If you have an electronic device, like a Vamo, it might be able to read the resistance and you wouldn't need a multimeter. As long as you check the resistance
before you hit the fire button, you will not damage your PV. Of course, if your PV does not read resistance, then you need something that does. One option is a portable ohm meter, which is available at several vape sites.
I was initially intimidated in wrapping my own coils, but I was scared into it by the FDA...and honestly, it isn't that difficult. There is a learning curve, with some frustration to overcome. But the good news is that it sounds like you have several devices already to practice on. Good Luck
EDIT: This is one of the first videos I watched for wrapping a coil. It is for a Phoenix dripper, which is somewhat similar to the Wyvern. I hope it helps or at least gives you a place to start:

This is another one for a dripping atomizer from awhile back, with silica wicks instead of stainless:
