This has been, by far, the best experience I have ever had dealing with a support entity in my long career in the technical arena
Not only wodSFTPdll is excellent, the service you have provided is outstanding and second to none!
It is very refreshing to find such helpful, knowledgeable and quick responding technical support.
Thank you for the great customer service ... I am really impressed with the wodSSH ActiveX control.
Thank you very much for the rapid responses. I was a little nervous about dealing with a company that is on a different continent from me. You have proven my concerns to be unfounded.
Your customer service was excellent, and I will look at your products in the future for precisely that reason.
Just thought you'd like to know that my gateway app with your SMTP Server component held the line against a DDOS attack today...
I can only hope I will have the pleasure to work with other products by "We Only Do" in the future.
You made it so simple for us to integrate SFTP - a technology we had little experience with...
Your professionalism is reflected into your email, your product and your web site. I am confident that these will make the difference.
