The AstroAI AM33B is the cheapest meter in this guide at £11.99 and it sits tenth of ten — but it is comfortably the most-reviewed product in the whole article. Its listing carries 55,860 ratings at 4.6 out of 5, which is more than the next two meters here combined (22,442 + 19,497 = 41,939). The breakdown shown on the listing runs from 75 five-star ratings down to 2 one-star ones.

What the meter actually does is narrower than that number suggests. It is a 2000-count unit: AC/DC voltage, DC current, resistance and diode test, plus dedicated battery modes for 1.5V, 9V and 12V, a backlit LCD, data hold, auto shutoff, a continuity buzzer and a CAT III 300V rating. There is no AC current range in the feature list, and no capacitance, frequency or temperature range anywhere in the listing. The listing also disagrees with itself on colour: the title says Black, the specification table says Red. Everything on this page is taken from the Amazon listing, not from our own testing.
