Voltage tester.
Handy tool for checking power in car.

Neat and easy to use
Very easy to use when tracing a tow bar electrics fault. Automatically detects voltage or continuity. Quick and handy compared to using a multi meter, the crocodile earth connection helps.

Useful tool
A gift so I hope it does what it should. It looks as described.

Easy to use
As described, prompt delivery, easy to use, clear display, useful cap for probe, led light is weak but better than none. Storage pouch keeps tester tidy in tool kit but it is a snug fit. There is enough room in the case to store a AAA battery separately either as a spare or to prolong battery life. Reasonable price.

Good voltage tester
For £13.50 this is a bargain. I usually use slightly higher end name brand testers, but this is a well constructed unit with a clear backlit screen. The safety tip to protect the probe pushing through the case is a handy feature, and the sprung wire to the negative clip is sturdy. The small torch at the front isn’t strong but is extremely handy when you’re checking fuses in a dark car boot. A much better alternative to the screwdrivers with the bulb in the handles.
