You just can't ask for more value for the price in this product. With this 6-pcs set you can easily cover a whole wall of your home studio and erase that flutter echoes and early refelctions of the room straightaway. To say something not as good about it, if you are wiling to put the 6 pieces close to each other, it creates a weird pattern since the edges' "cones" don't fit perfectly and you can easily spot the junction between both panels. Other than that, trust me: GREAT product.
