WeCooper Ducting Editorial Review
The WeCooper 100mm - 4 inch Connector with Backdraught Shutter has garnered a variety of feedback from customers, reflecting a mixed but generally positive reception. Many users appreciate its functionality, particularly in areas prone to strong winds, as it effectively prevents the backdraft of wind into their homes. This capability is especially praised by those who installed it between their extract hoods and external vents, noting a significant reduction in wind ingress. In terms of build quality, users have remarked on the component's sturdy Construction and overall good value for the price. The lightweight nature of the product makes it easy to handle and install, which several reviewers found straightforward. A few users, however, experienced issues with spring strength that affected the operation of the shutter; while some managed to adjust the springs for better performance, others had to use additional insulation to ensure a snug fit within the duct. Overall, the WeCooper 100mm Connector appeals to users seeking an effective non-return damper, though potential buyers should be aware of possible adjustments needed for optimal functionality, particularly concerning the spring mechanism. **
