Review: ممتاز قوي في الاستشعار
Review: I needed to replace one wired and one battery smoke alarm. The original First Alert unit was no longer available, so we opted for the recommended unit. It arrived in a plain cardboard box, but the device was sealed. We had to change the mounting bracket to adapt to the newer design, but the size and function remained the same. All in all, a good quality alarm that will hopefully last the same 10 years as the original.
