This is the second iGo product I've purchased -- the iGo adapter for my treo 700p failed within 3 months of purchase. The DC power cord from the unit to my Laptop failed after using it just a few times. Given these two experiences and finding several reports on the internet citing the same problem, I say iGo needs to engineer their products better.Another issue I have is the rather annoying reconfiguration of the tips: each unit has its own set of adapters. So, if your old tip fails, you might not be able to find a new tip that's compatible with your converter.To sum up: iGo sucks.
