Best microchip cat flap?

[Blinkingblimey]

Does anyone have any experience or recommendations as to which/which brand of microchip cat flap is the best? I am totally clueless and would be very grateful of any advice!!

We have sureflap, on our second due to a house move and more than happy with it. Haven't had a single intruder and batteries have lasted a long time

I've got sure flap - it is a little on the small size tho, not sure how my BSH will fit thru when fully grown.

Sureflap here too, had it in for about 2 1/2 years, no trouble. Battery lasted about 2 years. My cat got the hang very fast, despite being thick as two short ones, and with a (then undiagnosed) brain tumour brewing.

Fantastic thing, at our last house strays and young foxes were always getting in and she was so stressed.

Sureflap ordered - thank you all!
