We had a Staywell Infra Red cat flap for a number of years with varying levels of success.
It finally stopped working so we bought the Sureflap microchip cat flap as our cats already had compatible microchips.
It was extremely easy to fit (fits into the existing hole from the Staywell) and it works very well indeed.
The only couple of downsides I'd say are that the cat has to be right in the tunnel for it to work - but not a major issue as it is very responsive. Also, even though we bought the new 2010 version the draft proofing isnt great. For us, this isnt a massive issue as its in the kitchen, but if it were in our dining room for example, Id say the draft coming through the flap would be a major issue.
Overall though i've been really impressed by both its looks, ease of setting up and how well it works, so would definitely recommend this to anyone who already has cats with compatible microchips (check they are compatible though, not all are....)
