I have had the EQ 6 for about 2 weeks and within 30 min, I was able to design anything I wanted. It's similar to a CAD design software. I feel that it is worth the money and the price is within reason when you think that designer Engineer software cost several thousand of dollars.
I think it has help me from making lots of mistakes as you can change the colors around and the setting of the blocks. I used to make a sample block to be sure what it would look like. Now with in a few min., I can see what it will look like.
