I've been using David's Delight plus for abt 1 month, I would give a 4-5 star rating on effectiveness of product. I'm docking a few stars out of frustration in dealing with so many wires and 9v battery ... it seems a product design is stuck in the 90's. I would love to use this product more ...but I find it too much of a hassle to carry about and set up. For the product cost... I would like to see more modern tech implemented.
