You take the top and inner cover off your colony and put this "small super" on top. Fill it with 2-one gallon zip lock baggies filled with 6 pints of syrupon top of the frames. Cut two 1-1/2" slits on the tops of each bag. Run a little syrup into the bees so they will know it is there and you will be amazed at how well this feeder works. You put 1-1/2 gallons of feed on a colony at a time. Fill the bags at home and take them to your bee yard in a box. You will love this method of feeding. Click Here for Instruction Sheet
The wood is low grade with several knots and the grooves that are made to hold the frame together break easily. The final product is decent, but I do wish it had been labeled Some Assembly Required in the first part of the description. It is in the instruction sheet link, but I missed it. I purchased this thinking I would save a little time and work, however, it would have been just as easy to pick up the lumber and make it myself. Over all it will probably last forever and serve its purpose well.
