The first thing I noticed when I opened the pouch the pen was sealed in was the aroma. It was strong. Straight away it reminded me of the CBD flowers I have previously used. I liked it. The pen itself is small and sleek which makes it easy to hold and use. The pens sleek design also means that it is easy to take with you and keep in your pocket un noticed if you want to use it through out the day. I liked that I didn't have to charge the pen up and wait to use it, and there's no settings to mess around with. You just take the pen out of the packaging and you are good to go. The draw is very good and it usually takes three pulls before the pen gets up to full strength and you get yourself a thick plume. So be careful if you are a none smoker, that third pull does have a slight kick to it when it is up to strength; Definitely a throat tickler. Flavour wise I was definitely impressed. I have used a few CBD vape products and none have tasted this good. I genuinely felt like I was using my old PAX 2 vaporiser, I loved it. If you are after something that has that natural earthy CBD flower flavour then this pen is for you. Honestly, try it, you'll enjoy it. The pens longevity depends on the usage and how it is used. I used my pen a lot and I do enjoy large, thick plumes to get that relaxing effect from the CBD; so I managed to get three days use out of my pen. If you want to get more days out of your pen then I suggest you don't get carried away using it like I did :)
