My vape of choice is POTV Lobo, it does a great job especially with the dosing caps, It's a bit harsh though so it's best used through a bubbler. You can use it without though, but if you like a dark roast then you really will need to reach for the glass. It's easy to keep clean too. The swappable 18650 battery makes for great sessions if you want to climb that temp curve slowly. This use case is where the main negative comes into play. The session time is too short. I think they've had to do that to stop it heating up too much, that's just conjecture on my part. As I've told all my colleagues I use it openly sometimes with a little silicone bong I carry around in my bag. The secret to its use is your battery management. I have 7 cells on rotation, a six pack waterproof carrying case and when I charge them at home, I'd recommend using a plug in (mains) charger. The USB ones are nae good. If I could afford it I'd get a Venty but if you are on a budget the Lobo is by far the best out there, the Hybrid heating chamber and the removable battery make it the perfect choice for someone like me who can be away all day but not necessarily near to a electric supply.
