Fast shipping, received the S300 in 3 days. Very easy to install, I used a spare E-ZPass velcro stickers to mount the S300 behind the rear view mirror instead of the 3M sticker pad that came with the unit. Great tech support from Ray, he answered my e-mails within 24 hours and provided options on how to get my S300 to power down whenever the engine is shut off.

I tried it...first two weeks were tough..itched more each night I continued to use it.....I did not give up..By week three..I noticed a BIG difference in my awful candida symptoms. Today..(one month later)...I have no itching issues like before. I also see a difference in my skin tone....and I can sleep at night! I have not slept well in YEARS...I say try it..for a month (at least)..before you give up on it...Initially..your symptoms may get worse before they get better..
