Rat flap
So far so good, keeps rats and mice away, very happy with it. Fits well and does what it says. It was easy to install and good value for money.

It really works!
Really successful solution to our rat problem. We needed 2 units as the rats were coming from 2 different directions in the sewer pipe. Nothing else had worked to keep them out. Now we don't get any and it worked immediately. We even bought a spare one to use if necessary, as can't do without them! Highly recommended solution.

Very short
Itโs a lot shorter than expected which makes it difficult to fit, also the wire tether should have a smaller fitting for the bolt Time will tell if it works

Seems to work
So far so good. Installed 3 weeks ago and no sign of rats as yet. Had 2 previous issues with rats chewing through toilet outflow pipe. Easy to install and fingers crossed this is an end to the rat problem.

Not appropriate for 4 inch pipe - too small
Says suitable for 4-inch sewer drain pipe, adjustable. It isn't, simply not wide enough unless you stretch it or pack.out the pipe end by conceting it in... otherwise you leave gaps that aren't impossible for vermin to get past. Go for proper bigger size one up to 110mm, I wasted ยฃ38 on this via Amazon. Had in box new and unopened too long so couldn't return it.
