It has been over two weeks since I ordered my DaVinci vaporizer and I still haven't received it. I even opted to pay extra for "expedited" shipping, which has proven to be anything but. Dealing with DaVinci customer service is a horrific experience since there's only a chat option and no way to actually talk to a person to quickly resolve an issue. After spending 45 minutes on the irritating chat interface with a representative they said the delay was due to a warehouse move, and they would refund my expedited shipping fee, and that the vape would ship within 24-48 hours. It didn't. When it finally shipped about 72 hours after the chat it seems like they didn't send it by expedited shipping as it has been with USPS for over a week at this point. I actually had a Davinci vape before and loved it. After using it regularly for ~3-4 years I decided to upgrade to a new one, and was looking forward to the new model. At this point I'm not even sure I want to be a customer of a company whose service is so bad. In 2023 "Expedited" shipping has come to mean within 24 hours of placing the order, with delivery within 2-3 days of that for a total of 3-4 days from order to receipt. Most e-commerce stores offer far better than that so that's a bare minimum for what "expedited" should mean. Currently I'm at 14+ days with no sign of the vape on the horizon. Truly disappointing. Can't really answer most of the questions below as the delivery hasn't even happened yet, though the survey about how my experience has been is. It has been incredibly disappointing. Based on past experience I'm hopeful the product will be good, if it ever gets here.
