Functional
Used it well to re-connect several small cat.6 cables from a long one. I did have a problem pushing the daughter guide into the end of the connector, which is necessary for a good crimp. I had to use a thin screwdriver to insert on the sides inside the rj45 connector to finish pushing the guide to the end. The other problem is that the tab that secures and prevents the rj45 connector from coming out of the port it is connected to is not working properly, it is too low and needs to be lifted by hand, carefully as it is fragile.
