I've had one for the past couple of years. I got it because the power in my apartment at the time was beyond atrocious. It made a huge positive difference. Everything was much more refined and focussed after I put the VansEvers unit in. I haven't compared it to other conditioners to be sure that it is the best out there, and I can't say it will definitely work for you. I can only say it worked wonders for me and that Mike is a good guy to deal with. If you get one straight from him you can also ask him to tune it to your preferences.
