    Rolls RS81B reviews

    RS81B Quartz PLL Synthesized AM/FM Tuner is rated 2.0 out of 5 by 1.
    Rated 2 out of 5 by from Not Recomended Purchased 3 of these units. All 3 failed in less than 12 months. When the first unit failed is when I discovered the warranty is only 90 days for what Rolls' calls Signal Source devices. Despite each unit failing in less than 12 months and this comment I found on the Rolls' web site Regardless of age we don't usually charge for repairs, a lot of people really like this. they still charged $50 - $60 dollars to fix each unit. They seemed like a nice unit but 3 strikes is enough. Gonna try a different brand next time.
