Easy for Lazy Birdwatchers, Just Pour and Go
Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
It doesn't get easier than this hummingbird food. There's no messy mixing or measuring, and there's no harmful red dye that hurts wildlife. My hummingbirds seem to love this food, so I keep buying it. It's not inexpensive but it is a quality product. Note that sometimes the packaging from Amazon leaks. This isn't the manufacturer's fault. I love this hummingbird food and am a lifelong customer.

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.

Very good ... but beware.
Size: 64 Fl Oz (Pack of 1), Style: 64 oz Ready To Use
First of all I just want to point out all of the reviews from people who claim that the bottle arrived damaged or open and in some cases ruined the other products shipped in the same box. Amazon will not issue a refund for that, which is absurd. My bottle arrived in good shape although the top was loose - not a big deal. The formula itself I find to be the best out there. I used to buy Pennington, which until this year was a deep red, now it is a light orange. The hummers will not stomach it. This product is better than the older version of the other brand.
Taking one star off for all of those people who got a damaged bottle that would not be refunded.
