The Aecity Upgrade series features a hybrid construction, pairing an ABS plastic head with an aluminum shaft. This aluminum component is designed to conduct vibrations into the ground more efficiently than all-plastic alternatives. The 8-unit set is intended to cover up to 5,000 square feet, though this range is highly dependent on the moisture content and density of your soil.
The solar panel on these units is a 2V/45mA polysilicon model, which functions best when it receives at least 8 hours of direct sunlight. Features include a variable frequency pulse ranging from 400Hz to 1000Hz. This variation is designed to make the environment less predictable for visiting rodents. It is important to note that the buzzing sound produced by the internal motor may be audible to humans and pets in very quiet outdoor settings.
Build quality highlights include a corrosion-resistant aluminum stake, but the plastic head housing has a wall thickness of less than 2mm. To ensure long-term usability, it is best to place these units away from the direct path of lawnmowers or heavy foot traffic, as the plastic can be susceptible to impact. The internal 600mAh battery provides the power needed for overnight operation after a full day of solar harvesting.
Summary: A sturdy option for clay-heavy yards that utilizes aluminum for better vibration transfer, provided the solar caps are protected from physical impact.
For users who prefer a more subtle aesthetic, the green-cased 8-pack offers similar functionality while blending more naturally into the grass.
