This product has a flaw that, unfortunately, has compromised the integrity of my Sony Ericcson 810i mobile phone. I ordered two of them for two family members. The first time I used the first one, just 5 days ago, when I went to remove it, two clips disassociated from the charger and remained in the charging port of the phone. These are very fragile plastic clips. I had no choice but to push the charger back onto them in the hope that they would click into place on the charger itself and be able to be disengaged from the phone. This has happened only with one of the clips. This means that I cannot use the house charger or the music earphones with my phone. Further, I have to remain with this car charger attached to avoid having that single unmoving clip break off in the phone port, thereby disabling the phone seriously. I have reported this problem to Sony Ericcson by email. The other charger has remained unopened until I sort this out.
