Review on Optical Ethernet Network Analyzer for Portable Disorder Testing, Measurement & Inspection by Tres Carmon

I bought this tool in August to use in another house. I arrived at my other house at the end of October. I have been trying to use this device to trace Cat6 cables in my new home for the past 48 hours. In that short time I changed three 9VDC batteries in the transmitter, the latter only took 10 minutes to "scan" before the battery died. Of course I can't return it because it's outside the return window, although I haven't used it until 2 days ago. Worked as stated. I was happy with that. Until I see him eating batteries. By the way, the batteries are so hot that at first I was afraid to even touch them.
