I like everything about it except the fact that it is very difficult to turn the plastic container counter-clockwise hard enough to depress the engine turn-on metal button down enough to let the on/off nob work. You need 4 hands to do it - 2 to hold the base so it doesn't turn when the other 2 are twisting the plastic container counterclockwise. I have to use my elbows to press the container against my belly. Sometimes that twists it enough so the motor will go on, but the container isn't closed tight enough and the contents leak (or pour) out. please fix it and send me the retrofit before I wear a hole in my belly.
