I bought this pair of chargers for my HTC pocket PC phone. I don't know how well it works for devices that take proprietary chargers (like the Motorola Q phone or those mentioned by other reviewers). What I do know is that, before I found this item, I was paying $15 per charger, and now I'm paying $4-5 for two. So far I've been using them for several months without any problems. Both chargers work as well as the expensive ones did. The home charger is pretty small and the plug extends sideways, making it good for tightly spaced outlets or certain power strips.
