Ok so I have been using a lavatube V2 for about 7 months now.. Well I work in receiving for target and have broke so many carts on my pv.. All the lifting bending and boxes pressing against my pockets is causing my tank to bend breaking the seal at the bottom of the cart where the cart meets the lavatube.. I have went through so many carts its not even funny.. I don't have a car and we don't have lockers to to put our stuff in so I have been stuck leaving it in my pocket while I work.. Well today I ordered a Vapor Zeus from V4L. Now while this unit is a lil pricey I am hoping that I can keep it in my pocket with out breaking it everytime I bend or squat.. I wanted a unit that had the power of a VV but was smaller and easier to use and have while out and about.. So If anyone has used a vapor Zeus. And can let me knkw how it works for you and if you think it hold up up in my pocket at work I would be truly grateful.. Also how long are the tanks lasting for you you?? I Also boughr a 510 to 808 adapter hoping to using the carts on my lavatube when at home.. do you think it will work????
