"Bought these to fit the RJ45 plugs also bought. They worked OK for what I wanted and did what they said they would on the instructions. When stripping the outer cover you have to be careful not to press too hard but this is stated on the instructions. If you are careful they work well and fitted the plugs that I needed to. Can't advise about reliability as only bought them this week."
"It is a very good tool for making of RJ45 ends, the only issue I had is that the cutter for removing the outer sheaf is a little bit too close and can cut the inner cores so ending up going back to my side cutters for the initial preparation but the tool is excellant for crimping the ends."
"after wasting about 20 rj45 plugs and alot of cat5 cable, i had have a closer look to see what was going wrong. Maybe i had the only faulty crimper in their range? I realized that evry time you aply presure, the teeth slide into the side of the metal contacts of the rj45 plugs and actually pulls have them out rather than compress them in."
"The crimping tool is too flimsy - looses alignment and even with a lot of fiddling it's really hard to get a rj45 plug crimped on with all connections working... Spend a bit more money and get a better bit of kit - mines going in the bin."
"This tool is simply not robust enough, there's too much movement in the pivot of the tool and the teeth which depress the pins of the plug when crimping slide down the side of the pins as mentioned my other reviewers.
I only wish I had read the reviews before purchasing as I would not have wasted my time."
"I bought this as I only had a few cat5e cables to make up.
First cable had a few unmade connections after checking it. So I thought my technique was out.
2nd cable wouldn't even crimp the connector to the cable.
On looking at it closer, the tool had actually become misaligned i.e. both handles were no longer square as it had bent in the middle. This may well have been my fault for squeezing too hard on the first cable bot there is no way of knowing how much pressure to use.
I ended up buying a ratchet type for under £20 that actually makes the connection coming down from the top rather than from the side. The difference is unbelievable."
"What do you expect for £12? Decent RJ45 crimp tools like Molex cost ten times that and no professional installer would use these. The crimp tool market is flooded with cheap imports because no-one wants to pay the proper price. If you just want to do a couple of crimps, they are OK, but definitely not day-in day-out use."
