Ecoey Smoke Detector, 10 Year Fire Alarms Smoke Detectors，Smoke Detector Battery Operated with Photoelectric Sensor, Fire Alarm with Low Battery Indicator, Smoke Detectors Used in Home, FJ138, 4 Packs

Review by GreenCountryTables com - These were super easy to install with the 3M double sided tape that came with the item. Batteries are included. I had all six unpacked and installed within 15mins super easy. The outside casing plastic, great quality. Impressed with inexpensive cost and great product. JesusLovesYou

We bought a 4 pack. These are SO easy to install/put up. The powerful stickers on each side, combined with a magnetic piece makes so much sense and gives flexibility as to where you can mount the detector. White as white (not off white or beige) was exactly what we wanted. They are small. Batteries all worked fine and the unit itself is simple/nondescript, so it blends in. Very loud. Totally would be these again!

Easy to assemble, great for rental houses.

These are much smaller than typical smoke alarms, very loud, the only reason for the -1 star, all the included batteries were dead on arrival

Good enough for my rentals, and good price

So far these are working really well for us. I like how small they are.

I installed 5 of these yesterday following the instructions and doing the test beep. Today we were cutting floor trim in one of the rooms with this product. A chop saw will create dust and smoke. This detector 3 feet away did nothing, nor did the other 3 nearby in other bedrooms. HOWEVER I did not throw away my old smoke detector that was sitting rooms away and guess what! It went off! So these are a faulty product that do not detect smoke in the same room. BEWARE! These will not save you in a fire. Terrible product the manufacturer should be ashamed for selling a faulty safety product.

Great! Easy to install, great small design, and loud.
