The hummingbird feeders I bought from them leak right out of the box. I spent weeks trying to figure out a way to do the leaking, but to no avail. They won't even offer me a courtesy exchange. They told me to fill the feeders halfway and turn them up. Essentially : you can use them to hold nectar or you can use them to feed hummingbirds, but not both. They are unprofessional, snide, and disrespectful. I wish I'd read the other reviews of the website prior to wasting $200 here. I'll pursue a credit card claim, but I really shouldn't have to.
