Does what it needs to

For the price (Was £9.99) the length you get is great. It's very thin and transparent which makes it nice and easy to hide, although this makes it somewhat fiddly. Apart from that it does what it needs to. Used to extend sky hub.

Excellent product but fragile!

Thiis is a great product for extending your phone line almost invisibly. However, it is so invisible make sue to attach it securely with the double sided tape provided, because a vacuum cleaner sucking it up is the end of the extension! Also avoid sharp items under carpets like gripper rods or nails. I speak from experience!

Like the fact it's clear plastic so it doesn't stand out going round walls from socket to wifi hub.

does this affect the router signal

does this affect the router or telephone signal. . . will i get less signal on the computer

1 Answer

You should not notice any degradation of your internet connection. However there would be a slight reduction in "signal" to your PC or Router. You should not notice this however. It is important to understand that if you have to makewiring connections with this (or any other phone extension cable) then the connections MUST be secure (viz the wires must be firmly inserted in each crimp/slot).

Can it be cut?

I only need a 6 metre long extension kit. Can this be cut? Thanks

Thanks for using Argos Q&A.

I have investigated the matter for you and can confirm that the Masterplug 15 Metre Clear Compact Telephone Extension Kit technically could be shortened. We would advise against this however, due to the precision need to re-solder the connector back on to the cable. Also, if cut/shortened the warranty of the cable will be voided.
