We have the sureflap connect, and also have individual feeders for each cat... no stealing the others food.
The door is great, but... it is not waterproof like it says. If it is not installed in a sheltered area water will track in at the bottom of the tunnel and eventually short out the antenna loop.
My first one suffered from this when it got wet when we had a contactor clean the windows. (a smear of silicon around the joint fixed it, but I replaced it anyway as I was going away for a week at the time)
I find the batteries last around 4 months or so, I do find for some reason one of the cats info does not always get uploaded to the cloud, the door always activates properly just no data stored.
Lastly, the cat we had when I got it took weeks to get the idea, I taped the door open for a week, then disassembled the catch and ran it like a normal door for a week then added batteries (so it made the noise), then added the catch back... and still had to do a lot of coaxing, she still couldn't get the idea. To this day if I set it to allow cats inside and not out, the slight difference in operation means she can't work out how to get in.
Our second cat.. pushed him through one way and called him back... job done
Seconding that they're not waterproof - mine only lasted about a year in a location where it occasionally gets indirect water ingress. Have been using it as a very expensive manual door ever since...
