See; Edge isn't bad. I love mine and have had no issues.
check these qoutes: "take the edge off, it it jacking with your stuff, unplug it and everything will be fine. i would throw it away. this is why i dont like them, they are not reliable. talk to edge they will work with you on getting it replaced. they are good people",
"it is the edge box, not reliable at all.", and "this is why i am going to get mechanical guages and going with smarty's so i know exactly what is going on and can trust them a great deal more."
This is why you have to take everything you read in a forum with a grain of salt. People are quick to jump to conclusions and treat everything written as the hard truth. Remember, not everyone posting to forums know what they are saying.
They often post opinion as fact.
