Review: Great little tester - Why did you choose this product over others?: Fantastic product, use everyday, like how it’s pocket sized, just wish it did a continuity audible beep Functionality: Great for proving dead on a circuit when you haven’t got your tool bag to hand Value for money: Very good product for the price
Review: Mini backup tester - This tester really is small ( I'd call it a pocket tester ) and that's the beauty of it - Easy to carry with you or good as a little backup tester as there's no batteries required with it - It's nothing fancy, just a large LED display and no audible tone, but it does the job - The probe shrouds ( Grey on mine ) are easily removable for socket outlet testing ( I will mention though that I trimmed the RED & BLACK probe insulation back a couple of mm and formed a bevel before the probe tips and, for me, this greatly improved it's userbility for socket testing - For the money you really can't go wrong with this little tester.

## Questions & Answers

A: ET45 had a CATIII 350V rating so if your planning on using a 600V proving unit probably not. Try a known 230V power source.

### ⭐⭐⭐⭐ Very small (smallest tester I ever saw)
*by N***L on 7 April 2023*

Short leads but the item is so small it fits in your pocket like a set of keys. If you want really small testers to give a clear indication of voltage these could be right up your street. A few sparks loved how small they were . Ideal for occasional use or part of a survey kit
