Testo 0590 7450 745 Non Contact Voltage Tester with Built in Flashlight, 1" Height, 1" Width, 6" Length, Black

Low-pass filter shows. Sturdy built product.UPDATE: after two weeks buzzer started to sound somewhat raspy, like something came loose in tester's white cap and rattling. It goes away when I hold it on one side and comes back on the other. The product works fine, but rattling is distracting.

First of all, do you have to read the entire miniature print to even figure out where the battery compartment is and how you access it. Then you have to have a tiny screwdriver and the screw is very hard to get out and once you get it out it’s very hard to get back in. Good luck.

White tip came apart and broke after 2 uses. I thought the product would be more durable.

Other then the shipping issue, ( post office was late) the product is good quality and durable. So far its been very accurate. I'm very happy with it.
