Neither wait for the sig Tmax it's amazing ss box
mod which is vv/vw and has rms.

I agree with this. The Segelei Tmax should be on the market in the next 2-3 weeks. Should combine the best features of both the MVP and the Smoktech VV Gripper. It will use an 18650 imr battery. Not sure what the eventual price point will be.
I have the Gripper and a Segelei/Ovale V8, another gripper-style box mod. I like everything about the Gripper except for its cheap body and body parts. The battery door is very fragile. The top connector on some models is wobbly. The fire button is cheap feeling. But the design and form factor is ideal. Just wish they had made it of more durable parts. I had my first one for 7 weeks when all three front buttons fell into the body. It was still under warranty, so it was exchanged for a new one. I like the 18650 battery for all day use.
The Segelei/Ovale is plastic, too, but appears to be made much stronger and better with better fitting and functioning parts. I'm not aware of any vendor currently selling these at the moment. It uses two 18350
batteries for all day use, too.
The MVP having a metal body makes it more durable to the two above mods, but I'm not a fan of the proprietary batteries. Once it has run its life, there's no way to replace it. At that price, I want my mod to last longer than an eGo battery. I would have prefered the option of a replaceable rechargable battery.
