    Great Spotless System

    Posted by Brad on Sep 28th 2020

    Very impressed with my spotless tank, works as advertised. Would really like the option for a wall mount or portable cart mount with it. I also purchased the bypass which was effortless to install and after unboxing was ready to wash within 5 minutes. Thank you!
