Awkward fitting because of plug size.
I already had two smoke detectors fitted 20 years ago of the same manufacturer. The new ones didn't come with a back plate and so I had to adapt the existing one's to fit the new alarms. This was because the plug in on the new ones was considerably larger than the old ones, which made them difficult to fit.

Does the job
The only demerit is that their white and my ceiling's white are very different whites. One oddity: The test button only tests this individual alarm's siren, not the others in the circuit. The others test the entire system. Thus it makes you wonder of there is a misconnection

Will no doubt work satisfactorily, but cost-cut design compared to predecessor model.
By buying the same make of alarms to replace time-expired ones I had hoped fitting would be the same. Sadly not! Diameter is smaller and cable entry point totally different. This left unsightly marks on ceilings which had to be repainted. Also the small T-shaped locking tab is a ridiculous design idea - cheap and unsatisfactory.

A flat design looks beter on ceiling than the previuos one
as I was changing the old one fitting of these were quite simple , though I thought the instructions on the wiring and linking were a bit difficult to understand could have been clearer especialy about earthing.
