These port covers are so much better than the ones that come with the feeder. The original ones were too easy to get off by a crafty critter. These fit so much tighter and no critter will be able to get them off. At times they are a bit snug but that's a good thing. We learned you have to squeeze them in the middle to pull them off.
It is very good! The covers are great!
These new covers are awesome. I was having trouble with the old flat ones, the rats figured how to pull them off. With these new ones, they seat real deep in the ports and the rats haven't been able to pull any off!! These are great.
They do the job.
