WLNYUGS SP-BF-5 Hanging Metal Bird Feeder

Bird: The WLNYUGS SP-BF-5 is a hanging metal seed feeder with a gravity-triggered spring closure intended to deter squirrels. A clear seed-level window and claimed 8-cup capacity could reduce refill checks, though customer feedback is mixed on loading and perceived size.

Pros and cons

What to know before buying

Listing details to confirm

Listing details are inconsistent: the technical capacity is 1.36 kg, while feature copy claims 8 cups or about 3.5L. It describes a clear PC tube although the listed material is metal, calls out three ports, and separately lists an AC power configuration despite describing a gravity-spring feeder. Pole mounting is mentioned in feature copy, but the listed mounting type is hanging. Confirm which details apply to the selected model. Customer feedback also includes mixed reports about filling difficulty, size and durability, so check dimensions and expected use before purchase.

Customer feedback highlights perceived squirrel resistance, construction quality and general functionality. Reports on filling are mixed, and some customers say the feeder is smaller than expected, with durability opinions also mixed. The positive feedback may matter to buyers seeking a squirrel-deterrent feeder, but it does not verify the claimed spring mechanism or resolve the conflicting capacity details. The overall rating distribution is mostly five-star, with ratings across the full range, so individual experiences are not uniform.

Positive themes

  • Customers describe it as effective at keeping squirrels away and appreciate its construction quality.
  • Some customers say it works well.

Negative themes

  • Some customers report that the feeder is smaller than expected.

Mixed feedback

  • Some customers find it easy to fill, while others find loading difficult.
  • Customer views on durability differ.

Frequently asked questions

How does the listed squirrel-deterrent mechanism work?

The listing says a gravity-activated spring system closes the ports when a squirrel triggers it, while birds can feed. This is a manufacturer claim, not a verified performance guarantee.

How much seed does it hold?

The technical details list 1.36 kg, while feature copy claims 8 cups or about 3.5L. Those capacity claims conflict, so confirm the applicable figure before buying.

Can it be mounted on a pole?

Feature copy mentions a bottom hole for pole mounting, but the technical details specify Hanging Mount. The listing does not confirm whether pole-mounting hardware is included.

What is included?

The listed contents are a manual and bird feeder. The listing does not specify pole-mounting hardware.
