Update: These guys saw my first 3 star review and legitimately sent me 10 emails (one every two days) to stalk me. They said they didn't like my 3 star rating and wanted to refund my money. Normally I understand the feeling of compensating someone for bad service but these guys harass me directly by sending email after email to make sure I got the previous email. I know the tactics people use to get people to remove reviews and I firmly believe the only reason they want my money back is because they want me to give a 5- leave a star rating. Guess what? You do not deserve it! I'm fed up, I don't want returns, and now I think this crimp kit is worth even less. I just want to be left alone and don't want to be bothered with a negative review. Old Review: Everything is good in the kit except for the Cat5e connectors. Connections are terrible. The metal pins to be crimped are too thin. They are thinner than standard pens. This makes it difficult to actually crimp with the supplied crimp. I suggest buying other plugs and throwing away the plugs that come with them.
