My bullseye started acting up, around the end of summer, had to push the switch several times, for it to make contact. I knew there was an issue with these switches, so I e mailed Whites, they said mail it in and we'll fix it no charge. I finally got it in the mail LOL (procrastinated). Well we will see what the future brings, Whites is said to have excellent service !! In the meantime, I bought an automax v-4, its WAY bigger than the bullseye, the belt clip on it looks useful, gonna have to wait till spring to use it though, we got 12" snow on the ground !! By then I'll have a dx-1 sunray, and wont need either one !! good for back ups or tag along guest diggers !!
