Product Description
Cable stripping should not be too short to enable trimming of excess cable during crimping.
Cable stripping can be done diagonally for quick and precise insertion into the crystal head.
Ensure proper insertion of the crystal head into the crimping cavity to avoid damage.
Tips: When crimping, you can twist the wires together to make it easier to cut the 8 wires at once.
1 3 in 1 RJ45 Crimper 2 T-568B & T-568A 3 How to Use 4 Suitable Connectors
RJ45 cable sequences (T-568B and T-568A) are sticked on our product.
Apply sufficient pressure during crimping to ensure smooth and secure contact between all terminals and the network cable. Fully open the handle of the crimper tool before removing the crystal head to prevent it from getting stuck.

Quaility with the right price.
Good quality item just like the last one. Had to share the purchase with my work colleague.
Ehsan –
Not bad
Not the best quality, but it helped me to find the issue and I was able to fix the ethernet cable problem

Good price
Bought as a backup as my others have stated to not cut the cables through [hit and miss] on first try these didn’t cut through 100% 2nd try was better so will update review after used for long periods
Mark H –
Great product
Works as expected
Fred –
Badly built crimper.
Bad built quality. After using it for a month, the cutting blade on the pass through end started to cut into the crimping tool itself. Its badly built, there is a grove to avoid the blade cutting into the tool, but it does not align properly with the blade.
Amazon Customer –
Great tool and worked well.
The crimping tool is excellent, the end connectors are a bit different and tricky at first to get the wires in correctly, but once you work it out it scrimps securely and didnât have any failures.

Do NOT buy, the plugs are totally useless. They do not make reliable connections.
This is not a cheap product so I was expecting a bit more from it.Firstly the wire cutter struggles to cut pure copper cat5e strands. This shouldnât be the case.The wire cutter has no facility to measure the correct wire length to fit exactly into the crystal case.The wire stripper doesnât work on standard unscreened cat5e cable. Why not?Apart from the above, it comes in a nice case, it was supplied with a separate wire stripper which works really well. The tester isnât anything special but it does the job.In summary, it does what it says it should, itâs just not anything special. I think Iâll be looking for a future purchase to improve on this tools lacklustre performance.Update 9th Feb 2025Been having a nightmare job trying to get connections made using this tool.It appears that the plugs once crimped do not make contact to the socket pins in either the supplied tester or a standard netgear switch socket.Iâve dismantled several failed plugs and found it was possible to, by hand, pull out several wires. Whereas a properly crimped plug I hand to use pliers and the wire broke before the crimp joint failed.

Great crimper and connections

Activité minutieuse , matériel pratique mais attention de ne pas trop serrer la pince pour dénuder le câble, risque de cisaillement des fils
Naparima –
good product, does the job well and with ease
Simon Scott –
Seems to work fine until you try to use them for anything over 90mbps. I even tried them with different ends, but I have had the same issues
