I like the VIM. I wasn't thrilled with the off White color at first, but I was surprised how clean it stays. It has a smooth rubberized surface which has a nice feel to it. It is extremely lightweight for it's size with a comfortable ergonomic design.
The tank is easy to use, however the model I received does have a little play in it. I really like the big button. It's easy to use, so I have fired it by accident a few times, but I prefer that over hunting for the button.
