I got my FF2+ yesterday and will be writing more when I have spent a little more time with it but I am so excited about it that I had to post immediately. The two major improvements that I was interested in are both great! The battery lasted a long time! I’m not sure how long the original and FF2 batteries lasted when brand new but I remember being disappointed because they died before I was done having my first night with the vapes. Last night, I used the FF2+ for several bowls and the battery never died. That’s a huge good sign. The bigger holes in the screen make the airflow less restricted and it is very easy to inhale. This is important because a lot of people vape because they have sensitive lungs. I had a hard time with the original and FF2. I felt like I had to prepare my lungs to do hard work when taking a hit. I love the vape so I just got used to it but the FF2+ is so easy to draw a hit from. It was so easy that I was actually drawing too hard and fast in my first hits and it wasn’t working properly. I realized it was probably because the heat was going through too fast so I took a slower draw and it worked great. I will post more in a few days but my initial impression is great! If you have a FF2 already, definitely do the $30 service and if you have the extra cash, go ahead and get the 2+. You won’t be disappointed.
