Great little tester.
Bought this to help to identify the correct fuse in my car for a dashcam connection. It has proved to be ideal for the purpose and would recommend it for its ease of use and portability. Clear display and the fine tipped probe makes it ideal for those tight spaces.

A 5* product let down by a stupid mistake.
This is clearly a quality bit of kit, and is supplied at a great price. The unit comes in a small but perfectly sized zip case, and is very straightforward to use once you know what you’re doing.However, that comes with a big “But”, for which I have deducted a star.The small Instruction booklet lists several languages in the Contents Page, with English at the beginning.However, my copy inexplicably started at page 9 meaning there were no English instructions! Thankfully, I was able to find them on the internet, and I quickly downloaded them.A 5* product let down by a stupid mistake.

Is this useful to you?
Pretty accurate but of limited use... Kept in 2nd car glovebox. Taped cable ends to prolong life of tester.
