Excellent quality, very strong. it lodges the pump and still space for a net to catch large debris and a mat to catch smaller particles, it is very helpful since there is a large tree near the pond. If you are not a professional, watch out where to cut the liner around the opening, we have a few snags, mainly for not understand how it should be done. At the end everything worked fine.
