It performs the job well and is a lot better than the more expensive brands that Hime Depot and Lowes Cary. It has a controllable stripping depth that is a must.good product; works goodIf you just need a crimper you might be better off just buying a crimper and even paying a little more for it if you need it for professional use. For me, it cut well enough that I don't have a lot of negatives for the crimper. I know that seems contradictory that I'm suggesting you buy another product just for the crimper and yet I'm writing that the crimper is fine.I just needed this for a home project and didn't want to build a full kit just for one crimp so a cheap kit was good for me. If you are starting out, this might be a good kit for you also.If you already have a crimper and you are looking to upgrade, this might not be it unless you need a passthrough crimper. I myself already have a couple of crimpers but neither are passthrough and I don't have ends for my crimpers so this was a fast way to get everything.The tester didn't work for me and lights 2 and 6 just remain lit. I tested it with many different cables and two fresh batteries so it just seems like a dud. I'd get a better cable tester for a serious project since I'd be worried that these will die on me halfway through a project, or not at all. It would have been nice to test my cables but if you can run data at full speeds without weird disconnections issues, the cable is likely fine.I will say, the cable stripper worked great to take off the jacket from cables. I did about 10 ends and I never cut through any of the wires. I usually have to be more careful with other strippers.I didn't try the punch down tool yet but I've had to make do with the cheap smalls ones for emergencies and this can't be worse than that. I hope.I don't want to deter anyone from this kit. I would just say to set your expectations and if you're using this for a serious project, test everything to make sure it'll work for you.I wouldn't market this as a "professional" bundle, but it's a very good DIY kit. If you're creating cables for a living, spend the money and get higher quality tools to get faster, cleaner, and more consistent results. If you're making a few cables a year or running Ethernet in a home as a one time project, you can buy with confidence.Like that the color code is on the tool. A or B. Would like a pocket on the bag for more instructions for those of us who do not use it day in and day out so as to refresh memory on how everything works. So many tools for a reasonable price.What I was really after here was the crimping tool and the cable tester. The crimping tools is the type that lets you pull the wires all the way through the end and then shears them off simultaneously while crimping the cable. You can also crimp traditional ends with the tool. The first kit I received had, unfortunately, a bad cable tester. It failed after I put a new 9v battery in it and tested a cable by giving off a whiff of burnt smell and the lights danced around a bit, then stopped working completely. I notified Amazon and the seller through the return/replace this order tool and had a replacement kit in my hands the next day. I sent back the complete first kit, including failed tester a few days later and was not charged for the shipping. The other accessories in the kit are a bit of a bonus, I like the gray cable sheath cutter, after I figured out how it works, it does a really nice job of just cutting the sheath and missing the wires. The other cutter tool must be for coax, as it cuts to deep for CAT 6 wire. The screwdrivers were better quality than expected as well, with hardened tips and grippy handles. Haven't had a use for the punch down tool yet, but it looks to be pretty standard and of decent quality.If you are starting out and learning the ropes or just doing basic cabling. This pack is great for you. It comes with everything you could need to get started. I been using it for a couple of months now and it is still able to be very productive making cables on the fly.the only issues i found is. for the cable stripper tool, you need to adjust the blade as currently it can cut very deep and cut the individual wires. so it is best to adjust it with the screw driver till it extends enough to only remove the outer casing. the crimper tool, it takes getting use to if you dont push the rj45 cap in all the way. also the blade can miss if you don't like up all the excess cables. it takes getting use to because they have to feed thru a certain way for the crimper to cut off the excess wires.overall.. this is a great starter set. the blade is still as sharp as when i first bought the tools.Crimping tool is not good enough and tester is not working after 3 days of useCompact and complete. Worth the money
