There is an incredible difference in a $300 DJ for a 4 hour or so wedding and a $600 DJ for a wedding. What zeal does is use entertainers that are cheap and in DJ world the more you pay, the more likely it is you will have a better experience. It would not be a surprise if they downloaded all their music from youtube. Most people probably think its OK but it is terrible for businesses. Reviews may all be high but thats because so many people just say I liked the price and after enough 4's and 5's you end up with a 5 average so that you can say you are a 5 because you filter your results if you do bad... then you don't ask for a review and there is no harm right? Wrong!
