Worked Flawlessly
I was unable to upgrade firmware and/or control my iOptron mount with the KeySpan Tripp-Lite USB to Serial cable. It was suggested by iOptron that I get the FIDI cable instead. A member of our Astronomy club recommended Startech.....and the rest is history. I would not hesitate using this company for additional needs.

Com Port Retention makes life easier
We have several of these deployed and the Com Port Retention makes life easier for our clients - and we've never had a failure. So we are quite happy with this product.
