Delivery was the only issue with this transaction. I personally extended delivery 15 days and that wasn't enough time for the delivery to happen before Trade Assurance had ran out and the transaction was said to be completed when it wasn't. That's not right, especially when seller could have extended delivery time another 15 days BUT DIDN'T. That said, my humidifiers have arrived in good condition and I'm satisfied. I love this style humidified, just wish China was still selling them as I think I got the last of this style. Much thanks for making them available to me.
