I haven't used yet is why I gave 4 Stars but I installed to the back of my basket rack, I had to do some modifying to secure the plate but its solid and heavy weight and sits level, the ratio gauge is not marked so I added some white tape to the bottom funnel and marked it myself ( full, 3/4 1/2 1/4 and close ) also marked the opening plate, I left off the control handle because there is no way to install it, I don't understand that, so if I need to open or reduce I will have to get off the bike and move it to one of my marks, I sprayed the hardware with black Rustoleum to avoid rust, Once I've used it I will clean, oil and dry and store back in the box and keep in my garage, If ever stops raining I'll get an opportunity to use it, " Remember, your next successful hunting season starts with a great food plot", feed em all year.
