User Testimonials
This was one of several USB tools I have tried. It seems to be up to the task, and somewhat better than the others I have tried.
I was using it to troubleshoot a piece of MIDI equipment that sends it's data out via USB instaed of the older standard DB type serial connector. Worked great and quickly showed when packets were missing.
You have a very useful and well-designed product. Keep up the good work.
I am absolutely overwhelmed by the quality of the new monitor software. WOW!
I wish I'd had this years ago as I've developed about 20 USB devices and the corresponding drivers going all the way back to the original V1.1 era. At least I don't have to deal much with blue screens anymore (mostly).
I never understood why a CATC type hardware monitor was required. Your product seems easier to use and is a much better value. Thanks for the excellent support also.
It worked! And it was straightforward and easy to use at a time when I didn't have time for manuals with a deadline bearing down on me.
Saved my bacon, thanks very much. Nice bit of kit.

Top class product. Saved my day in detecting speed of my USB devices.
Thank you. Your tools are really awesome too I recomend them to every company I go to or do work for. Keep up the good work!!
Thanks for the quick response, I do not get help that quickly from other software companies.
I have been evaluating your Serial Port Monitor for about one week now, and find it the best product of its kind that I have tried. I am also looking at the USB monitor program and the network monitor.
