Review on 📞 UVital Coiled Telephone Handset Cord | 1.2-10 Feet Uncoiled | Landline Phone RJ9/RJ10/RJ22 4P4C Cable | Set of 2 (Black) by Tommy Willis

Don't buy this, its not worth the money or the degradation you are causing the customer and yourself. Problem with them cord untangles - they work fine for a month and then start falling apart when the cord is twisted and moved, the connections from the cord to the base are affected by movement when you are on the phone and this interrupts you from the customer you can't them hear or they can't hear you. Both have deteriorated. As far as I can see the ones sold here at Revain are probably all made by the same manufacturer so it will likely be the same one you are buying from.
