Well if there is something to worry about I will find it. This I am really worried about. Before even reading this on my first ever charge I noticed it was extremely hard to remove without the thought of something being damaged. So that in mind and after reading everything I can find I filed down my clips. I used a small grinder and just moved the clips close enough until they were almost down flush. I think getting rid if the hook part is the main thing. I did my CA-146c adapter first as it is easily replaceable and took the clips right down. It still feels very firm but not scary to remove. I then did the charger but left the now flat clips a little higher to get a slightly more secure feel. The CA-146c did feel as though in a car charging sutuation it may wiggle free, but then again maybe I was just used to the crazy tight fit before. I have not done my transfer cable yet but will do. I really didn't want to have to do this but being in New Zealand with an imported one (even though the retailer promised a local 12 month warranty) I have to do everything to prevent the usb port being damaged I can. I really hope it is not an issue with mine. My N900 was made in Korea 48/2009 2101 and the last 6 imei digits are 508395
