This kit is designed for a variety of uses, however some of the tools included are either of poor quality or will not provide you with enough use to justify the price of this item. The crimping tool is decent but not heavy. The wire tester/pair tester has first-class DIY quality. a crimping tool that got stuck during testing, a pair of screwdrivers, zip ties, and headphones for a one-pair analog line. All in all, this is a kit that only has a crimping tool, a huge body, and RJ45 connectors that are worth checking out. Everything else is very amateur quality and for this price you get much better content, I can't in good conscience recommend this at this price.
