I like it as a bedside mod and it works nicely in the car.
It is quite a heavy mod and when I go hiking the reo is in my man bag strapped to my water bladder bag.
Yip it's not really the size or the weight... it's only really because of how difficult it is to use. My SNow Wolf and SX Mini are also too heavy to go out with... I always leave the house with two REO's and occasionally my Sigelei 75. When I go to a vape meet I take a suitcase to carry the heavy mods.
