Review on 🔥 LCD Display Smoke, Heat, and Carbon Monoxide Detector Alarm - UL 217 & UL 2034 Standards Compliant by Brad Laverentz

Very small device. It took me a few minutes to figure out how to remove the back bracket to put in the batteries (2 AAA). Speaking of batteries, they don't give you any. I had to assemble a bit of the remote control to test it. Instead of a flat bar for the positive terminal, they have springs on either side so the battery doesn't want to sit flat when inserted. I tried to put my finger in to push it out and got a small cut. some hard plastic. I finally resorted to the tip of a knife to slide the battery back far enough for it to sit snugly on either side. Otherwise it would fall out easily. The instructions are tiny but readable. No instructions on how to remove the back to access the batteries. Tip, just push it to the side. It seems to be working fine, time will tell.
