Love This!
So I used to have the older version of this, whilst it had its flaws it lasted us four years and it worked well enough apart from the daylight sensor. I tried to buy it again after it cracked and found it discontinued. After looking at the reviews I got the sureflap one. The first one I got one of my cats could not get it open, she would scrabble at it and it was hit or miss if it opens. Ordered a second one and my other cat could open it when on the locked mode, even when it was locked both way
