Like many others, I was extremely nervous about sending my passport in the mail to Bangkok, so I read review after review after review just to make my brain say it was ok to do this, 555. Today I just received confirmation through Thai Visa Centre's status update tool that my NON O Visa was completed with pictures of my passport showing my Visa. I was excited and relieved. It also had the tracking information for Kerry (mail delivery service). This process was completely smooth and they said 1 month to complete, but it was only a little over 2 weeks to complete the process. They always reassured me when I was feeling stressed about the process. I highly recommend Thai Visa Centre. 5 STARS +++++
