It incorporates multiple side vents for air circulation. This helps keep the worms healthy. It also ensures that their castings and juice remain in prime condition for collection.

Despite the top-notch ventilation system, this vermicomposter is highly regarded as one of the best at preventing odors. A tight-fitting lid is thanks in large part for this.

Molded mounds in each of the 3 trays encourage worms to work upwards. They move to the surface to digest the most recently added waste. The multi-level construction helps move their worm castings and worm tea to the bottom of the bin for easier collection.

Collect your valuable worm juice with a screw-in cap. We like the fact that it’s removable as it helps prevent dripping. And less dripping helps prevent pests in turn.

The worm juice and worm castings can then be used as an earth-friendly, nutrient-rich fertilizer for your plants and garden. The fertilizer is 100% organic. It directly results in a greater crop yield as well as much tastier plants.

The product also comes with a 1 year limited warranty. The warranty protects you from manufacturer’s defects. You can rest assured that you get what you’re paying for when you select this particular vermicomposting bin.

  • Affordable – The product costs around $110. An alternate option that comes with 1,000 red worms costs $130.

The Bad

  • Unattractive – A bit of an eyesore. Unlike some compost bins on the market, this one isn’t very stylish. If you care strongly about your kitchen décor, you might want to store yours outside.
  • Lack of Wheels – This vermicomposter is heavy when it’s empty. It’s even heavier when it’s full of soil, worms, and waste. Moving it to a new location is difficult without emptying it since it doesn’t have wheels.
  • Difficult to Clean – Some users have noted that the side vents become easily clogged with residue. They’ve also noted they’re difficult to clean. Most users with this problem have been able to solve it by using a straightened paperclip or similar long skinny object for cleaning.
