The best cord ever
Size: 4 Pack (4 PCS), Color: Black
I'm so thankful for this cord detangler. This product works amazingly well. I never have to worry about the awful mess from the other tangled cord. Great product.

Best purchase
Size: 2 Pack (2 PCS), Color: Black
My phone cord constantly started tangled at work. I purchased this and it literally is the best thing I’ve bought! It doesn’t tangle and the length is perfect.

Not cost effective:
Size: 4 Pack (4 PCS), Color: Black
Bought on Feb 17th, both of the ones in the box are no longer working. One gives the caller a lot of static feedback, lasting a month. The other cord detangler just drops the connection. Two different problems and the reviews said motnhs to years. Mine did not even last months. Very disappointed.

Not sure. Swivels only worked for a couple fo weeks each in office environment.
Size: 4 Pack (4 PCS), Color: Black
The detailed swivels wore out pretty quick. Trying a different brand to see if that is just normal failure rate.
