Amazon Review April 25, 2014
Reviewer: R. Price
True, the base leaked like crazy from the split between the top and bottom parts. I was about to either return the feeder, or permanently seal the base with silicone sealer. Then I figured it out -- so I offer the following advice:
A. Before filling with nectar mix, first test the feeder with plain water (which I did, and found that the water leaked out in about 10 seconds). This avoids losing a batch of nectar by not understanding how the feeder works.
B. To test with water, and later fill with nectar, read the instructions (they're not too clear on the tag, but the video helps):
- Screw base together until snug (the halves do not form a watertight seal, and this is okay).
- Screw container into base until snug.
- Push container down into the base seal (may already be in down position) to close ports, and prevent base leakage when filling.
- Fill only half way [until hummingbirds have discovered it] & refrigerate the rest.
- Screw top cap onto container TIGHTLY [most important step; it must be airtight].
- Pull container up from base to open ports. The liquid will start to fill the base, and stops when the vacuum prevents further flow.
