Item was received in a sealed box. Electrical tape was provided with the item. Item has a blue back light with a digital voltage reading that was easy to read and was more or less accurate when compared with reading from my multimeter. Polarity feature works well and is pretty straight forward in terms of use . build quality is very good in my opinion and was a good buy

Nice packaging, nice feel, doesn't come off as cheap. In photo are this 3-72 volt along with HF tools pair even showing their cheapest one. All three work well. I never had a test light not work. The 3-72 has an included volt meter and polarity indicator. It will be a tool I use on occasion for those times I would like to diagnose gauge failures ie: low voltage or dirty contacts issues. Those cheaper ones may not light yet still pass voltage. I'll be using all three as needed. It would make a nice gift for those young mechanics still acquiring tools. Robert.
