One thing beginning vermicomposters should be aware of is pests, especially ants. You may need to place the legs of the bin in a water-filled baking tray or individual cups of water. The water creates a mote-like barrier that prevents ants from accessing the food in your worm bin.
This is an excellent bin for beginners, but you'll find your growth is limited. I couldn't find additional trays to buy on their website or Amazon. This won't be an issue for most people as two trays are plenty. Some people (me) fall in love with worm composting and want to grow their colony and composting power.
To do that, you'd need to purchase a fleet of these little bins or invest in worm bins with a higher capacity. I would invest in a few additional trays instead of buying a whole new system each time. You'll have to determine if this sounds like you and your goals for vermicomposting.
These are honestly minor issues. If you are looking for a small stylish worm composter, this is one of my favorite designs. Be mindful of pests in the spring, and you will be well on your way to composting success.
