I have a VTR and used for couple of weeks and left there collecting dusts. The only time I use my VTR is when I build the new coil or dry burn. It is very solid built mod and fires 0.8 ohm but it's kind of too heavy for me to bring out and about. If you don't like heavy mod I would probably recommend you look for something different. If you are looking for general use not sub ohm or high watts, then MVP should do the job. Mind you that MVP has the battery built-in so you cannot actually bring out with you while charging. Prox for VTR is that it uses 18650 which you can still use the mod while your other batteries are charging.
