Great quality, hummingbird nectar all in one bottle!
Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use, Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
I was so excited to get this hummingbird nectar because you don’t have to add anything to it at all. When I was reading the ingredients, it does have a preservative so that’s good as well. It won’t go bad on the birds. I love it. I saw my birds coming and going to this feeder all day. I highly recommend it.

Birds seem to love it!
Size: 16 Fl Oz (Pack of 2), Style: 16 Fl Oz Concentrate (Pack of 2)
I grew up using homemade hummingbird food dyed a bright red color with koolaid or food dye. But for the first time in my adult life, I'm somewhere that has a lot of hummingbirds and I wanted to provide them with the best juice possible.
I decided on this juice because I like that it has hummingbird friendly electrolytes and is in a concentrate so I can make my own preferred dilution. I am in a very hot desert climate so I've been doing a 1-3/3.5 ratio to help keep them extra hydrated and the hummingbirds and bees are loving it. We have four feeders. Two closer to the ground and two on our second floor balcony. The birds and bees have been visiting all four regularly and our cats are loving the show. I swear my youngest cat gets most excited about the bees.
I know the bees are seen as problematic for most but the birds don't seem to mind them sharing a few feeding holes and we don't mind feeding the bees too. The bees are probably more important for our ecosystem than the birds anyway.
I took away one star because the seals on the bottles aren't very strong and both had leaked during transit, one was very messy and crusted with dried sugar. Since these are technically supposed to be refrigerated after opening I probably should have returned them but upon reading the ingredients, I don't see a reason that they would have gone bad without showing obvious signs of spoilage. It's basically gatorade for birds. I even took a sip to see if I died. I was fine so figured it's fine for the birds too. If the next order is also leaking I'll consider going elsewhere but for now we have happy birds, bees and cats.

They keep coming back for more ..........
Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
I've only been using this food for two weeks, but the hummingbirds love it so far. From what I've read, they are attracted to the color of the feeder more so than the smell of the nectar / food itself.
With the amount of work that hummingbirds have to go through just to find enough food to survive, I figure it is worth the extra cost of this food compared to making plain sugar water that does not have the added minerals and electrolytes that this feed has to mimic real nectar.

Great product
Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
I bought this same product last year for my hummingbirds and it brings them into the feeder. So, as of today I have already seen a steady increase in the hummingbirds. 💕
