Hi Sythai Thats almost exactly what i have ok for once in a blue moon type wee domestic jobs but as the experienced boys say not much cop if u were using it often and useless to diagnose tricky faults.Ok if your on a strict budget and only doing domestic stuff.I store mine in a wee plastic box with clip on lids type of thing you use to put leftover foodinto the freezer in .I also carry a spare 9v battery in the same wee box handy for this lan tester and my continuity tester.

Have put my order in, if it's no good and need to find any faults then time to call a professional
