Review: Excellent Product - I purchased 2 or 3 of these add on handsets for my auto repair business. This is the second set I've purchased in the last 6 years. The first set had the same options but had an older product number. It was almost identical to my first set. These phone are hands down the best phones I've used at my business! They are very reliable even though the handsets had been dropped numerous times. They lasted longer than any other phone system I had prior to my first set. I was very pleased to see the new colors and construction upgrades to this system. I'm looking forward to using this system for some time to come.
Review: Not as described/recommended - This item is good looking, solid weight, and I was thrilled when I opened the box. HOWEVER, it was recommended in conjunction with the phone system I purchased at the same time -- it was shown as the "add-on handset" to expand the system I purchased ..... IT IS NOT ..... I am sure it will work fine with some other phone system, but it DOES NOT WORK with AT&T CL82321. Additionally - while the return process for this item was easy and absolutely no problem at all, getting the add-on handsets that do actually work with the phone system I purchased was a total nightmare .... after more than 30 minutes of 'chat' with 4 different CSRs, I gave up and ordered the handsets CL-80131 directly from telephones.att.com

### ⭐⭐⭐⭐⭐ Special item needed to be able to use these phones.
*by D***N on September 7, 2025*

Hard to find the items needed to use these 2 purple phones. So disappointing. Wish I could buy the answering machine in purple too. That will let my phones work.
