Easy to use and seems quite accurate so far. Speeds up fault finding massively. Very good price compared to elsewhere online.

My only complaint is that the jaws seem a bit fiddly, like they don't attach or conduct well - I have to grab components several times before I get a reading. I will look into upgrading these myself.

I passed the PE Power exam!!! I was a lot more comfortable coming out of this one than the FE. Please review EDIT 2/3 if you look at nothing else in this post There was a few items on the test that were just you had to have experience in the field for but I would say that was like 3 to 5 questions.

Other than that I have the 8 years working as an electrical designer(but it is mainly upgrading existi
