Review on Boost Your Connectivity with Optimal Shop Portable Wireless Network by Chris Bowden

Pros: It's cheap Seems to work well Cons: It has an annoying beep (with every keypress) that can't be turned off (I disabled mine by physically disabling the beep) It forgets Your configuration settings (e.g. meters/feet) on each power cycle. Ultimately, this is still highly recommended. If you have a bad crimp it will tell you which end is bad. Standard testers will tell you you missed a line/pair, but not which crimp is bad, and Murphy will let you cut the good end first every time.
