My EZ took a dive out of warranty but Edge gave me a reduced price towards another purchase. My EZ started to work only sporadically. My reduced price was probably the retailers wholesale price. Instead of getting another EZ I went with the Comp. The Comp is the same as the EZ in settings one or two. You have to tap the pump wire to use settings 3-5. Add a Smarty to the mix and you get some real power.
Be prepared to have a hell of a time getting through to anyone at Edge. Don't bother to leave a message in the general voicemail because no one will call you back. E-mailing is also an exercise in futility. Trying to get through to Edge is really hit or miss. Once I finally got a hold of a person I experienced even more delays. I asked to have the Comp sent Next Day Air and they sent it Ground Ups instead. I was told several times my EZ would be looked at the next day and it didn't happen. Bottom line, good product crappy support.
