Hey there everyone, I'm new here and I am looking for some help on making my first purchase. About 3 months ago I got to hang onto my friends vaporizer and I recently gave it back. I fell in love with it, and now that it is gone I'm looking to buy one of my own. The one I had for the 3 months was the arizer extreme and was really pleased with it, but for me, I want something portable and a tad more discrete. Something small, compact and effective is my style. I would also like something below or around $150. I've done some research and have picked three that really caught my eye and would love some input and maybe even some suggestions to other vapes that I might have over looked! 1. Davinci (http://tinyurl.com/l7rtpvm) What I like: Size, heat controls, looks to be well made, oil cans. Concerns: Read some people having issues with outgas, how durable is it? Hows the battery life? How easy is it to clean? Are the screens replaceable? 2. Vapir NO2 (http://tinyurl.com/l6trtqo) What I like: Heat controls, has some pretty good reviews, okay size, replace battery, price. Concerns: Doesn't seem to be as well made, also read some problems with outgas and battery. 3. Vapromax V Flowermate (http://tinyurl.com/lje6n2d) What I like: Really discrete, looks pretty well made, like the mouth piece compartment and the light. Concerns: No heat controls (not to big of a deal), not much information/reviews on it, how easy it to clean? Battery life? How durable it is it really? Replaceable screens? I am aware of the MFLB. As pretty and awesome as it is, I'm looking for something a little more technologically advanced. Thanks for your help in advance!
