## Customer Reviews

### ⭐⭐⭐⭐⭐ Surface warter drain issue.
*by J***G on 16 November 2024*

Since installing this product we have not heard any creatures. Very effective for what we needed. Highly recommended for keeping any uninvited guests out. Very easy to install, a little expensive but worth it. Looks like it will last for a long time.

### ⭐⭐⭐⭐ Seems to be working correctly. Price is steep for what it is but appears to be doing its job
*by M***E on 5 November 2021*

East to install but expensive for what it is.

### ⭐ Overpriced, didn't work
*by E***R on 30 September 2022*

Overpriced, poor quality and didn't actually do the job designed to because is was made considerably smaller than advertised.
