I 100% reccomend buying one of these, even if you're not an electrician, as internet providers (like mine) charge your $75 to do a job you can learn to do in 10 minutes with the same tools they use for way cheaper. This kit contains more than enough tools to get the job done. The RJ45 tool is really good quality and I love the addition of the wire stripper and cutter at the bottome of the handle (do be careful with handeling as cutting yourself is a risk). The testers are very helpful to ensure the wire works properly especially when you're routing them through walls and not sure if it was severd anywhere. Honestly can't complain about anything, I will definitely be using these for a long time.

My crimpers mangled the rj45's every other crimp.

good value for money

Very nice product and fast delivery! It will be nicer if the crimping tool also carries color code reference of the network cables.

did not come with instructions on how to strip the wires, don't know what tool does what,
