Thank you! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality and great price *by M***X on April 27, 2026* So far these have worked very well. ### ⭐⭐⭐⭐⭐ Excellent phone *by G***N on March 6, 2026* I got this to replace another phone of the same model. It's easy to set up, and the instructions are easy to follow. The buttons are easy to press, and are back lit, so they're easy to see in any light. The sound is good. It is Good quality. I would recommend this phone. ### ⭐⭐⭐⭐ Quality, cheap, cordless phone *by W***W on March 21, 2018* I was shocked when one of my colleagues said, "You should get a home phone." I already have a home phone, it's laying here on my desk, sometimes it's in my pocket, it even goes to the bathroom with me. My cable company gives you a discount for taking the home phone service with your cable and internet. Believe it or not, it would make my bill go up if I dropped it. I chose this cordless phone because I didn't want voicemail and I've always had good luck with AT&T products. It works very well but it has a few annoying parts that made me take a star off. I have had this phone for 7 months and still have no idea how you adjust the ringer volume. I've read the pamphlet. I even once got it to work and turned the volume all the way down so now it barely makes any noise (probably better that way). It does light up when it rings and I have it on my office desk so the ringing volume isn't that important but for others it might be. I haven't tried most of the features since I'm only using it for business calls. The call volume is excellent but I will say it takes some getting used to using a receiver like this when you're used to cellphones. All in all, it gets the job done and is a good buy for the price. ## Frequently Bought Together - AT&T EL51103 - DECT 6.0 Cordless Home Phone.
