Trintion 20Pcs Pond Protector Cover Net Floating Water Fish Pests Guard Grid Floating Heron Deterrent Device for Ponds and Water Gardens

Reasonably good; used in a small irregular shaped pond and easy to install. Taking a tip from other comments on Amazon I assisted flotation with cable tied corks at various positions and I believe this is beneficial. Fish so far safe from cats and herons and no visible netting which was the main purpose.

A bit tricky to assemble but seems to provide good protection for fish

Used product on 6’ pond, time consuming but long lasting. I used some from last year with new ones and all floating well. Absolutely perfect for all leaves except silver birch which get underneath - but quite easy to slip net underneath to collect them

It took us a long time to join these together. The pins that came with them are not suitable so had to use cable ties. Good coverage but they do sink. We attached string and supported to the ends of the pond. First use so see if they survive the winter

I had been recommended these as THE way to prevent Herons getting into a pond, so put my faith in this advice and bought 2 packs!!VERY disappointed. The sections are very fiddly to put together, and then easy to come apart. Also as soon as they went into the pond they sank in places!! ….not the product I thought it was and so reverted to using netting!

Better for larger fish , we lost 5 gold fish to the heron , looks good, floats well and still allows us to feed the fish without moving the floating structure , our lilies are growing through it too . Well worth buying

Did not like them much, not for my pond.

Good idea , keeps leaves out of water and no congealed mess
