I am an Electrician and I have installed much more expensive smoke alarms in other peoples houses. In my house I installed 5 First Alert Hush Button Smoke Alarms for [$] each from Target and I am very Happy with them. It has been 6 months so far. I would recommend these to anyone. Very Good Product. I also like the Hush Button feature on these. I was cooking in the kitchen and I set off the alarm. On my old alarm I had to take the alarm down and disconnect the battery until I got done cooking. On this Hush Button type all I need to do is push the button and the alarm goes into a standby mode. After 10 minuets it turns itself on again. Very good product.
I find the convenience of a ten year battery worth the price of the alarm alone. I wish they came in multiple packs as we purchased five due to requirements of new construction. This product takes off the pressure of changing batteries and annual maintenance.
