The cable works good the only dislike I had with the cable was no instructions or disk for drivers came with the cable. I went to the MFG web site and trying to find the drivers for this cable to be compatible just about drove me nuts. After much frustration and digging I finally downloaded the correct drivers and was able to use the cable.

It's does what it's for, I used it to connect a machine to my computer and it works great

I returned this item, so I can't review it specifically. I'm writing this to warn you that it's not the same as a VGA-USB connector. I'm basically computer illiterate, so I went to Best Buy for some professional help. I needed the VGA adapter, but when I saw the price, I asked the associate if they had any less expensive. He pulled this off the rack. I opened it and saw that it looked similar to the VGA connection, but because the box said PDA/Serial Adapter, I questioned him. He said, "Yep, trust me". After driving home (30 minutes) I discovered it wasn't right, the number of pins is different. So an hour later, I arrived home with the right product. Be careful of the associates' supposed "knowledge". I had to give it stars, so based on other Dynex products, I'll assume it's good.

I picked one of these up to connect my AutoStar telescope to my new computer for programming. I plugged it into my USB port, waited a couple of seconds until Windows told me it was ready, plugged in my telescope, opened up the AutoStar software, and was all set to customize the programming of my telescope. I'm very pleased with this little device.

Serial to USB adapter worked great. Windows 8.1 pro found it without any trouble. The cost was about twice as much as my normal supplier but I didn't have an option
