Ok I normally do not write a recommendation. EVER. However, this seller is pretty good and they certainly take care of the issue right away. I ordered 2 sponge filters from them and one was damaged in shipping. I sent them a picture of the damage and offered to return the broken one and they said no need and shipped me a replacement before they even emailed me back. I know a lot of there products are super inexpensive imports but for a beginner or someone trying to grow quickly, these folks are great!! I just ordered an air pump from them and will likely continue to use them.
