I received my Flowtron BK-15D shipment on the 5 July (order on the 2 July). Had the device out of the box and into its temporary place (awaiting Achia TSW-37 91 single pole for hanging) at 3pm. Turn device on and left it running until 7:30pm. Enjoyed a bug free afternoon on my recently renovated patio. I highly recommend this product for those looking to purchase a bug zapper that works as advertise and doesnt cost over $50 dollars.
