Aegis
Advertised as "The most durable vape booster". (wow) The battery compartment thread of my Aegis wore off within a month when changing the battery once a day. Now the cap won't stay on, rendering the whole mod useless. Cheap materials, bad design. Aegis not recommended. ---- Added approximately a year after writing the review: This review was written specifically about the Aegis mod. The tank that came with it is what I'd consider a five-star product. I'm still using it up to this day!
