Sooo, a couple of weeks back I wrote a quick little review of the DaVinci. Well after using it for a week, it BROKE!! Yes, I pressed the power button to start heating the chamber and it got to about 275 degrees and then the temp started to drop. It dropped back down to room temp and pushing the heating button did nothing. It stopped heating up! Unfortunately, the store that I bought it from did not do exchanges so I had to contact the company. To their benefit, they have been really great about getting back to me and I have sent the vape back (at my own expense) and am currently waiting for them to ship out another. In other news, before I even bought the DaVinci, I had been eye-ing the Pax by Ploom and was really bummed when every site that I went to had apparently been sold out. But just as I was browsing aroung vapeworld.com tonight I saw the little note that the Pax was IN STOCK and shipping immediately. Fearing they would sell out soon I placed an order instantaneously, so hopefully next week I will have two vapes coming in and can do a little comparison review... Stay tuned
