I absolutely love mine. I have an TW0J on mine and use it exclusively with bare 18650 cells. It is my favorite and most used light.
I find the two button interface perfect for a flashlight. I wish more vendors would follow this "trend" as it is extremely easy and intuitive to use.
I use it every night in my house, and it has replaced my U2 for this use since the two button interface is easier to use than the selector ring in the U2, and since the extremely low levels are even lower than on the U2 so with the VB-16 you can dial-in exactly the amount of level that you need, and lastly since I can stand it on its tail and light a kitchen, bathroom, etc., which is something I can't do with the U2.
It is a phenomenal light for the money and although my U2 has a ver nice neutral tint, I am seriously thinking about selling my U2.
