The SOLO S-2 is a great little device. Today I was cruising down a moderately hilly two lane highway with the SOLO mounted high and on the visor when I got a single bar K warning so I reset my trip meter. After 2-3 seconds I got another at two bar signal strength, then another, then another, then a constant after 10 seconds then full blast K. The LEO was hiding in the bushes at the bottom of the second hill waiting for a good speeder to nail. I measured 7/8 mile of range which is pretty good considering he was over the second hill and at the bottom shooting upward. At that moment, I was happy that I purchased this little beauty as my "second" detector. (My other is a V1.)
Just wanted to share a good experience in case anyone is thinking of getting a SOLO S-2 and were afraid it wouldn't protect adequately. I think it's amazing considering it runs on batteries and you can conceal it fairly easily.
