I've had this kit for just short of 2 months with constant use, and I'm very pleased with it. It's very convenient to be able to charge my Treo from my work computer's USB port (I wish the cable that came with the Treo could charge from USB...) and to be able to easily grab the cable when I need to take it home rather than crawling under the desk to unplug an AC adapter. I guess those who've given a negative review ended up with defective ones, but mine has none of the problems they've described. It plugs into the Treo securely and reliably, even after 2 months of very frequent attaching and detaching. I was pleased enough with it to order a second one to keep in my laptop case for when I actually travel (since my current "travel" kit has become my general charging/syncing kit for work).
