I’m giving it before out of five instead of five out five. Absolutely love the vape. The construction is next level. However, it’s not the most user-friendly unit. This is my first dry herb vaporizer. And I haven’t quite figured out how the app works how the pre-programmed settings work, etc.. I wish there was more info available. I’ve watched some short videos, but they were not the most informative. I’m sure I will get it figured out eventually I’ve only had it for about a week and once I figure out the features a little better I will be glad to come back and give us a five out of five. So far great product I just turned it on and go with the pre-program setting. I absolutely love the terp. flavors I get from this. and again, very impressed with the construction.
