I've had my ego-c twist 1000mah since early aug.(I have two). I have had no issues besides one of my atty's not making contact. When I first got them it would take about 2.5 hrs to fully charge them. The last week or two I noticed its taking longer to charge them. Its taking about 12 hrs now and I'm wondering if they are starting to die or is it the charger? I dont like to leave them on over night but this one has been on almost 24 hrs. Any ideas? If its time to replace I think I'm ready to move up and get something nicer.
