Review: Easy to use, good quality - Excellent value Ease of use Connection quality Quality Fit Yes I know, I've used the prompts below the box, didn't use functionality until now😁 I don't claim to be an Openreach engineer, but yeah the installation was a great success from start to finish. I think I'm right in saying, if the line fault is between your property and the BT cabinet, you have to pay at least £100 pounds for them (Openreach) to repair the fault. I live in a flat (apartment) the telephone line had been damaged by a rat I think, so I repaired it, and it cost me 80% less to fix.
Review: Great quality cable and Great Clips too! - I see from other reviews that some have problematic clips and some have a problem with the IDC insertion tool. I had no such problems. The supplied cable (I ordered 10M white) is very good quality with 2 twisted pairs. The outer sheath is easily to strip and the inner draw cord aids further stripping well. The cable is round in cross section. The IDC tool is all plastic but does the job well with no bending of the tool. The supplied clips hug the cable well and go into plaster easily with no bending of the nails. No need for a trip to the DIY store for further clips. The supplied grommets are made from rigid plastic and appear to be good quality. I didn't need the grommets, as I wasn't taking my cable through a wall. The included "instructions" are a little dated but may be useful for some as a guide to colour coding. All in all very pleased with my purchase.

### ⭐⭐⭐⭐ Good quality cable and clips. Punch down is useless.
*by F***Y on 15 July 2019*

We had a intermittent fault on our BT line that engineers said they couldn't fault. I replaced the cable and moved the box where it was actually convenient. in a corner out of the was not sticking out in the middle of the room where furniture would go. The cable quality was good quality, and used some of the clips. The punch down however was useless, I have used plastic ones in the past, but this one just kept buckling when used, so I used my professional one I had stored in my old tool kit.
