After waisting time and money on the H/L smokers with their noisey pump systems,the wicks that suck and the messy oil it is such a pleasing thing to have a smoker that works so well.The last new Tank I purchased was a Jagdpanther with the proportional smoker which lived to the ripe old age of two hours then nothing.I have 5-Worthless smokers,and they are good for nothing,but this unit which installs in minutes and runs silently and with such control that when I drive forward instant smoke and it seems to hang behind my Tiger like a cold day in Feb.1943 on the Russian front.Perfect effect for a Grossdeutschland Tiger just waiting for some T34 target practice.1-happy Saxondog
