Query: Product is not as advertise, poor quality and over price.

I purchase this product from Air & Water, only use a few times within two month and the heater is already broken. According to Air & Water review, their products are from the best qualities but if you ask me, the quality on this product is worse than cheap quality product and it's over price. It doesn't last. This is the worse product I ever purchase and it was a gift. I request a return from Air & Water, and suprisingly they do not supply you with the return label. You have to pay for it plus the shipping charge of $6.95 on the replacement. Base on the shipping rate on Amazon, 3-5 days shipping only cost $1.99 but they charge you $6.95. I don't think I would be buying this product or buying from Air & Water anymore. They have false advertisement on their product.
