Review on 📞 Landline Telephone Handset Cord Detangler Combo - Uvital 1 Pack 8ft Uncoiled Cord (1.2ft Coiled) with 1 Pack 360 Degree Rotating Swivel Cord - Anti-Tangle Telephone Cord Untangler (Black) by Raquel Peterson

Don't buy this, it's not worth the money or the degradation you are causing the customer and yourself. The problem with these cord untangles is that they work fine for a month and then start falling apart as the cord gets twisted and moved, the connections from the cord to the base are affected by movement while on the phone and you cut yourself away from the customer, you can him don't hear or he can't hear you. Both have deteriorated. From what 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.
