Customer Ratings & Reviews

These couplers are both high quality and very easy to use.

Had to connect a wireless all in one printer to my computer. I set up the phone line per instructions and nothing happened. I had a single to 2 line connector and tried that. No luck. Picked up this in-line coupler, hooked it up and printer, fax and computer are all happy and so am I.

It worked! My land-line phone now has great sound and the Coupler lengthened my land-line cord. The gold-plated connectors help to ensure a longer product life.

Needed to hook up a fax line to a phone outlet across the room, so used two phone cords and connected them by the coupler. Worked perfectly.

Needed a coupler to run a landline along with a credit card processor that used the same phone line. This worked perfectly!

I purchased this product to use two accessories for my Valentine One radar detector that recieve power by connecting mini RJ-11 cables to the unit's lighter adapter. This coupler did the job and worked perfectly. Because of this product, I can use both a canceled display unit and V1 Connect bluetooth module simultaneously.
