Quality and great price
Quality made as usual it is likely Chinese as the Chinese manufacturing has increased it's standards of product and style for Western markets, which is great because we get products like this that are really useful, work perfectly while looking and feeling professional. Lightweight but not cheap feeling, for the price another fantastic product that I wouldn't normally buy but will also last me for the rest of my life.I bought it to use for rewiring my guitar but having bought a solder iron as well, I might get into basic electronics and have some fun making some basic circuits while using this to keep me safe from harmful accidents.The screen is large and the display is easy to read while the dial has so many different options really a professional or an electrician would know better what they will all be used for.The leads are good quality and strong and plug easily into the meter when needed.Another great product from Chinese manufacturing, thanks

Ridiculously good value for money
Having been involved in (electronic) instrument technology in the past, I found myself becoming a bit of an equipment snob. Tektronix for oscilloscopes, Keysight/Agilent or Rhode & Schwarz for spectrum analysers, Fluke for Digital Multimeters etc. These things cost many hundreds at a minimum and many (many) tens of thousands at the top end. And then we have this AstroAI which I bought for £8.49.It does everything it is supposed to, does everything a Fluke Multimeter (which I also have but wanted something more chuck-around-able) does. I am actually quite shocked as I thought anything at this price must be some sort of junk prize from a Christmas cracker but it's not. It's a fully functioning Digital Multimeter for the price of a Big Mac and Fries.I haven't tested the full accuracy yet but it is accurate enough for the majority of tasks outside of a laboratory and certainly for working on the car or around the house it is more than sufficient. Having only had it a short time I cannot attest to the reliability but at the price, even if conks out eventually, it is not exactly going to be a financial disaster.So yes, if you need to measure the mains, a voltage across or current flowing through/to a battery, check switches, fuses, appliances, check which wires are connected to which others in your car/house etc, I can recommend this unit. It even has a backlight so you can do it in the dark!

Simple, cheap - for the amateur
I wanted this to test my car battery, I don't need an expensive FLUKE etc and I am not a professional!So for the DIYer probably this is sufficient, I'd appreciate clips rather than just prongs as its safer and easier to use and would cost a few peanuts more. Does the job, compact but would be better is a soft pouch was included to keep it plus the leads in.

Cheap, perfectly acceptable quality and accuracy for home use. Recommended.
Very cheap, reasonably accurate, small and does what it says on the tin. You're not going to use this to help test and design the latest iPhone, but if you fix electrical equipment at home, or work on car electrics, this is a perfectly adequate tool. Even the stand works OK.

Not an electrician or mechanic ,but can use this easily
Great piece of kit. I'm not a mechanic or an electrician , but I can work this. I've learnt AC / DC, resistance and continuity . Well worth £9 .

Super little meter!
A super little meter looks sturdy. Easy to operate but with instructions of you're not sure. Even comes with batteries
