Sherem DNA Helix Hummingbird Feeder review
I bought the Sherem DNA Helix after seeing a neighbour's tree swarming with hummers and finding out a spiral feeder was the reason. It has hung outside my kitchen window every day since.

The short version
A 23.5 oz spiral feeder with 32 flower ports that keeps hummingbirds in view far longer than any single-bowl feeder I own. Easy to refill, easy to rinse, and it only sells through the official page.
Buy it if
- You want several hummers feeding at once instead of one territorial male
- You are tired of unscrewing a sticky reservoir every week
- You want the feeder to look like garden art from the patio
Skip it if
- You want to buy it in a hardware store this afternoon
- You only have a windowsill with a few inches of clearance
Materials and build
The spiral is a single moulded red track with translucent chambers running underneath it, and a clear ring at the base that doubles as the ant moat. The whole thing hangs from a steel hook through the centre post.
Nothing on mine has cracked or gone chalky in the sun, and the red has not faded to pink the way cheap plastic ports usually do by August. The translucent chambers matter more than I expected: I can see the nectar level from the kitchen without walking outside.
The first day
I filled it, hung it under the porch roof, and had a female Ruby-throated at it before dinner the following day. That is faster than any feeder I have introduced to this yard.
What surprised me was the behaviour, not the speed. Instead of sipping and vanishing, birds worked their way along the spiral, port by port, which keeps them in view for a minute or more at a time.
Living with it
Refilling is a pour and a flip-top, so it takes about a minute. That sounds trivial until you realise it is the reason I actually clean it weekly instead of letting nectar go cloudy.
Every piece comes apart for rinsing under the tap. I use plain water and a bottle brush, no soap, once a week in hot weather.
Ports, ants and bees
The 32 flower ports are shallow and shaped so a hummingbird's tongue reaches the nectar without the bird contorting. As the level drops, they simply reach further in, exactly as they do with a real flower.
The ant moat has kept the ports clean on my hook. I do get the occasional wasp on hot afternoons, which is true of every nectar feeder I have owned.
Where it beats the glass bottles
Traditional glass feeders put every port around one shared reservoir. Five or six ports, one bowl of nectar, and one dominant male who chases everyone else off.
The spiral spreads the ports along a path, so the same bully cannot guard them all. That single difference is why my yard finally looks busy instead of contested.
The honest drawback
You cannot pick this up locally. It ships from the official Sherem page and that is the only channel, so if a piece ever breaks you are dealing with the brand rather than a returns desk down the road.
At $44.99 with the introductory discount it still cost me less than two of the glass feeders I had been replacing every couple of seasons.
