    Pros: Crimps well

    Cons: Doesn't strip Cat5 jacket that well

    I found that the stripping blade on this tool often cut past the outer jacket on 24AWG stranded Cat5e if I just squeezed the handle until the stop engaged. This was of course annoying because every time that happened I had to trim the compromised portion of the cable and start over. I found I had to lightly squeeze the handle and run the blade around the cable several times, which causes its own set of problems (i.e. incomplete or jagged cuts in the jacket). The stop is a piece of plastic which is held on by two screws. It may be possible to reposition the stop so that it works properly, but I only use this tool every few months so it's not worth the trouble for me.

    thrifty price for intent but short on basic performance needed

    Pros: Price is right for an RJ-45 crimper otherwise not readily found for 2-3 x the cost. With extra work and care can be used to do the job.

    Cons: Sadly, Shortfalls are probably why the price is low. It was a way to sell off a product that didn't make the grade in design and manufacturing. As confirmed by cons of other reviewers, the following defects are evident :1. Does not crimp well & you have to squeeze hard to get the clamp to work. 2. The stripper cuts the wires inside the casing so you have to be careful when cutting. 3. The cable stop for the stripper is too far past the blade so it strips too much of the covering sheath. You have to trim and re-cut the wires to correct length.

    Works Very Good.

    Pros: Strips, Cuts, and Crimps rj11 cable and connectors very well. Great Price!

    Cons: Strips too much length off of wire.

    This is a great tool to have for cutting, stripping, and crimping connectors onto rj11 cable. The only con is that the cable stop for the stripper is to far past the blade so it strips to long of the insulation off the wire. Then the grey portion of the wire is sticking out of the connector so after i strip it I have to use the cutter to make the colored wires shorter so the insulation can be crimped in the connector. Overall though these are very good at a much cheaper price than the local stores.

    This isn't as nice as the $50 one that I used to have. But for the price it is fine for people who use it 3-4 times a year.
