Maybe, but since you wrote that less than 12 hours after you had written ...Perhaps - but a quick look at the Fire angel products reveals that they are neither better or cheaper in any significant way.
.... I imagine that you can't be too confident about what you have now discovered by your 'quick look'.I know nothing of their products.
Having said that, now that I have looked and thought a bit more, I think you are right about price - provided one 'compares like-with-like', the FireAngel and Aico prices are pretty close.
In particular, as I wrote yesterday, the FireAngel SM-SN-1 appears to have an identical spec to the Aico Ei3016, both being mains-powered with sealed lithium (presumably rechargeable) batteries, and those two products have virtually identical prices - and the same for the corresponding SH-SN-1 and Ei3014 heat detectors.
The Aico Ei146e (mains-powered with non-rechargeable alkaline battery) (which you would not use) is a bit more expensive than the equivalent FireAngel SW1-R (and the same for Ei144 vs HW1-R), but Aico don't seem to offer an equivalent to the FireAngel SW10-R (or HW10-R) which is mains powered with a non-replaceable lithium (metal) battery (which, again, you do not like).
However, that's all about price. As for whether, when compared like-for-like, the Aico products are any better (or worse') than the FireAngel ones, I still have no idea, and I presume that the same is true of you, given that you "knew nothing" of Fireangel producs some 12 hours ago?
