Worth every bit of the money I paid for them and it didn't take me too long to put seven units up as I am 79 years old, the packaging was perfect and the instructions were very easy to understand but the printing is kind of small. I was really impressed with these units as they were better than anything else that I researched.

Nice Smoke Detector. Price was right.

Hard wired with a battery backup. Battery life is listed at one year which is great for a smoke detector mounted on a high ceiling. I like the "do not disturb' feature and the large button...easy to push with a broomstick or pole when the smoke detector starts to chirp in the middle of the night (low battery signal).

Easy to install

I recently installed the SITERWELL Hardwired Interconnected Smoke Detector (Photoelectric) and I'm very satisfied with its performance so far. The installation was straightforward, and the fact that it can be interconnected with other units gives me extra peace of mind knowing that if one alarm goes off, they all alert the household. The photoelectric sensor is a big plus because it detects smoldering fires quickly, which adds another layer of safety. The included 9V backup battery ensures the alarm keeps working even during a power outage—a key feature for any hardwired system. The alarm is loud enough to be heard throughout the house, and the build quality feels durable and reliable. Overall, this smoke detector is a great value for the price, and I highly recommend it for anyone looking to upgrade their home safety system.
