“Large transparent disc with drainage holes holds spilt seed. I have observed the birds eating seeds from the disc and the disc also prevents most of the spillage onto the ground. It screws into the bottom of the feeder with some fiddling so has met my expectations.”
“Great quality, so pleased I was able to replace my last one which has done me proud by lasting years. The pigeons finally cracked my last one but it did take massive battering. Looks to be same great quality so will extend the life of my bird feeder for some years to come”
