I got mine December 11th, 2012. So it's about 3 months old. It's a gunmetal V2, I use it mainly in 18350 mode, and despite having better quality devices I actually use my Vamo most of the time because of it's size, and quick/simple menu system, so it's got a ton of use on it. I use it, both at home, and I take it wiht me when I'm out and about quite often.
I have dropped it 3 times on concrete. One time it fell out of my hoodie pocket while I was getting out of a car, so a fall of about 3 feet or so. The second time I had placed it on top of a car, and it fell from about 5 feet. The last time was about a 3 foot fall again, out of my pocket.
I've dropped it on carpet and hardwood floors at my house more times than I can remember. I've knocked it over on my coffee table and had it fly onto the ground.
The device still functions perfectly. The 510 connection is still straight and in good condition, not worn or stripped. The screen has one gouge/scratch mark in it from when it fell from the top of the car. The bottom cap and top cap have a bunch of tiny gouge marks from falling and bouncing around on concrete. The gunmetal finish is wearing off with tiny scratch marks ALL over the bottom two sections of the device.
For some reason the main body portion which houses the board barely has any wear at all to the finish, it looks nearly brand new. The the two battery tube sections (the 18650 extension, and the same sized section that's above it) are the only ones that have the finish wearing off. I'm wondering if the base material is different, or if the finishing process was different between the two.
Still very happy with my Vamo and would buy another one if this one breaks. I'd probably go with stainless over gunmetal though.
