Perfect for testing batteries after Xmas
Was exactly what I wanted for testing a mixed box of batteries and sorting out the good from the bad. Easy to use and a great price too, very happy.

Simple and easy to use
Good basic multimeter, I am no expert but found this super useful and easy to use. Audio beep works well when testing. Unit is lightweight. flip out stand works well but do find I need to lay the unit on it side dependng on what I am testing.

Excellent inexpensive multimeter
Great piece of kit. Even comes complete with battery. Bought it as it was about the same price as a replacement set of leads for my old multimeter - a no brainer! Seems to work fine and I feel much more confident searching for live feeds as the 'pen' tester I bought keeps giving false positives. Obviously not up to pro work but for the average DIYer I give it a thumbs up.

Pretty in red and good value
Seems good quality. Not used it yet, but seems robust, good facilities and a nice colour

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!

Cheap but good little multimeter to carry in your tool bag
Cheap but good little multimeter to carry in your tool bag. I great, lightweight multimeter with clear, backlit display, and you can remove/replace the test leads if required (not hardwired like a lot of the other budget meters). I was going to purchase a Fluke meter, but as I am using it for work, I would be frightened of it getting stolen. This does the job nicely for me. Only one gripe is a slight delay waiting for the reading, but for the price you can’t argue.
