Summary: This is a solid product. I bought this to be able to connect/configure my Cisco routers & switches via the com serial port using my Laptop. It works flawlessly.

I could've bought a cheapie $15 alternative on FleaBay but the quality on all of those looked terrible and they weren't compatible with the new Windows Vista. Plus Quatech backs up their products with a 5 year warranty.

The only downside is that I think I should've spent the extra $7-$10 and bought the rugged version which is the SSRP100. I thought that this version would be ideal because the end cable is detachable in case I accidentally snap it off, I could always just buy a replacement cable. But it turns out that the rugged version is not a fixed attached cable but also the same detachable cable as well, except the rugged version is more durable. So far the performance is good but right now I'm scared to snap the end cable while it's attached to the PCMCIA card.
