Launched a new pen ? I have the model on the left for an year ,it is from CannBro . I think it is the best looking battery out there and matches my tinymight 2 perfectly , i got mine for 10 euro locally even came with a empty cart that matches . I find the 3,5 voltage too hot for most carts , i suggest to turn that down a bit if you wanna have a good product for double the price, people do rosin carts around 2v

! Autodraw function works really good though !
