Never had any issue with any Klein tool in the field. Would trust this for anyone in the field.

Yeah, but this one was posted by SD staff, so it's obviously the better deal.

I have this tester. Works great. Won't tell you which pins are bad, but come on, if there's a problem you have to recrimp the whole end anyway.

Thanks for saying this cause I personally like to see what pins are bad as sometimes just punching it down again will resolve it

Klein is the GOAT for these. If you are planning on getting this though, unless you already have the rest of the kit, I would buy a whole set of low voltage tools.

Agreed. About half the time if I get a bad reading it's down to one wire that just didn't crimp properly. I can see an argument that it may indicate a problem down the road if it didn't, but so far all the cables I have run are still going strong years later.

got same feedback from Keepa. There seems to be something broken with how slickdeals is getting Price Intelligence. I'd tag a mod or something here, but no clue how to do that.

I just use something like this, which is only $9 and tells you which pins are bad. https://www.amazon.com/TESMEN-TLP...0aWM&psc=1

This is the type I use too, but this has a low battery indicator and has the words "Klein" on it so you look professional like those guys that have Milwaukee branded pack out boxes with Milwaukee radios and flashlights.

I just watched NCIS Sidney and they used this exact LAN Tester to supposedly "hack" into a security camera network! Lol2
