I am now on my second warranty claim in about 4 months for this case.
The charge port is a very poor design, with two small plastic lugs that snap shut to keep the water out. They have a habit of breaking. My original case (ordered direct from LP) failed after 6 weeks. They replaced it FOC and now that replacement has suffered the same problem.
It is clearly a design fault and I found others on line who had had exactly the same issues. It is a shame, because the case is excellent otherwise.
I shall get a replacement but it will go on Trade Me and I will be moving to another case now.
