This product seems to fit snuggly into the port. I've purchased three chargers for my phone (E71 Unlocked) in a year and a half and this one seems to work so far. The original charger had a short, one car charger got a short after about year and felt loose and one that I recently purchased which is another car charger and it is loose and has an extremely short cordNokia DC-4 Mobile Charger(although very stretchy, but useless because it pulls out to easy).Pros: Charges phoneCon: Takes up two or three ports on power strip
