Brilliant basic tool
Bought this because I wanted to be able to test my car battery.In the box you get the multimeter, leads with probe ends and 2 aaa batteries.I've been so impressed with this.I've used it loads in diagnosing various faults on my volvo including dodgy grounds, shorts in headlight wiring, checking bulbs and fuses and resistance on various sensors.I've been playing with cars for years and I don't know how I ever managed without one !I would definitely recommend this, for the money it does everything you need.If you spent a bit more you can get auto ranging, but for car mechanics this isn't that important.For some jobs it'd be handy to have fine probes for back probing plugs, and crocodile clips would be useful-but I can add these cheaply as the plugs are universal.If you need a multimeter or want to try playing with a budget one I can't recommend this enough.Has definitely saved me money by helping me accurately diagnose faults

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!

Excellence right from the box
I’m an amateur budget audiophile who needs to know the continuity and the polarity of my speaker cables, the battery charge in my remote controls , the presence or absence of electricity in certain situations, I need to check the resistance in speaker in headphones, etc. Thanks to Amazon best choice suggestions I found this little gem of a multimeter who fulfilled all my humble expectations and desires. The build quality is good, the lead cables are soft and floppy, the probes are good. Amazing quality for amazing bargain price! Strongly recommend by me.

Check your car battery before buying a new one.
Had some corrosion on my car battery terminals and was starting to notice some odd errors in the car. Cleaned off the corrosion with a bicarb soda/water slurry and a small wire brush but was I still worried about the battery.Bought this £8.50 multimeter and tested the battery and it came back at 12.5 meaning all the cells are working fine. Any less and it would have meant one or more of the cells could be damaged and the battery would need to be replaced.Buying and testing with this little multimeter first, saved me £150-£200 on a replacement start/stop car battery.Great product.
