Just did my first service with the Bug Duster. First, the appearance of the Bug Duster is underwhelming at over $400 in cost. You will have to get over the initial feeling that you have been "hosed again with another equipment farce." The Bug Duster worked very well for me and delivered well. I really like the light that is a part of the system. I like the way dust products can be delivered to the target areas in manageable amounts. You can control delivery. Worked great on my first service. Now, we will see if the Bug Duster will stand up over time and abuse. How did Bug Duster makers come up with the price?
