After several years of modifications, I'm now getting around to documenting all of my experiences and posting them in one place. I'll fill this in as I get time. First and foremost, I'm not sponsored by anyone, nor have I been asked to write a biased review of any product listed. I'm an engineer, and honest data is worth more to me than a small discount.
The thread will be organized into categories similar to Zpost. I'm aware that certain posts will be extremely long while others may only have one post. I'll take requests for reviews of specific products first. Thanks for reading!
