Excellent value for money
A brilliant little machine which has been updated since previous purchase. Dials are now colour coded and easier to read. Excellent value for the money.

Great cheap multimeter
If you are a hobbyist or doing a small job at home, this is a great option especially if its on sale! It has all the basic reading options that is expected from a multimeter. It is decent quality with a decent build quality for the price. The stand feels a little flimsy, but works fine if you're gentle with it. It is really easy to use and easy to read as there is a button which can light up the screen really bright. I wouldn't mind paying a little extra for a better stand, but its definitely not a deal breaker! The accuracy is definitely decent too, not 100% but close enough to get the job done, especially for hobby projects. I recommend this multimeter to anyone who is looking for a beginner - intermediate multimeter, I would definitely get something more expensive if I were an expert, but for anyone that is not an expert, I would definitely get this multimeter. The value for money is too good!

Well designed and good quality. Don't be put off by the price
For years I have been using a very high quality Fluke multimeter but it recently failed/needs to be recalibrated. Having an urgent job to do I decided to purchase the number 1 rated multimeter on Amazon. However, I was concerned that the item listed only cost £10.49. Despite being suspicious that the highest rated product cost so little, I decided to trust the market reviews and bought one. It arrived the next day and I was very impressed. The black plastic case with integral stand was robust and was housed in a bright yellow rubberised protective case. The leads were of good quality not the usual plastic rubbish that one associates with low priced products and they were supplied with protective caps at each end. The device is well designed and comes with 9v battery fitted and a low battery warning symbol on the display. It has two buttons one for backlight on the LCD display and the other a data 'hold' button to freeze the display. It has three jack sockets one for Volts, ohms and mAmp, one common and one 10 Amp inputs. The rotary dial has 20 settings which include DC voltage at 200mV, 2V, 20V, 200v and 600V; DC Current at mA for 1.5V battery tester, 2mA, 20mA, 10A, AC voltage at 200V and 600V; Resistance at 200 ohm, 2K ohm 20K ohm, 200K ohm and 2M ohms; a Diode test and a Transistor hFE test setting. I have not tested the accuracy but the stated values are quite acceptable. Don't be put off by the low price. In this case low prices does not mean low quality. The Ultrics UT0021YB is a very good quality, compact and functional unit.

Accurate and easy to use multimeter comparable to name-brand multimeters.
Bought for testing connections on my e-bike and it works surprisingly well for the price. Tested the accuracy of it with a borrowed Fluke multimeter and it was just as accurate. It's small, easy to carry in a pocket, and the backlight can be seen in full daylight, so it's definitely bright enough for working out in the field. The provided cables are long enough for most uses, but you can use longer cables if you require it.

Reliable and Simple Multimeter
I’ve been using this digital multimeter for about 2 years, and it does the job well. The readings are accurate enough for everyday use, and the backlight on the LCD is handy. It’s straightforward, durable, and has held up over time. A solid, reliable tool for basic electrical testing with an ideal size.

Great for voltage leak testing in my aquarium
This thing is perfect for hobbyists like me who aren't professional electricians but need something reliable and straightforward The build is solid with that orange rubber casing that protects it from drops and the backlit LCD is good when working in the dim light near the aquarium stand The large display makes readings easy to see at a glance It comes with decent probes and all the basics: AC/DC voltage, current, resistance, continuity diodes and transistor testing. What really sold me is how well it handles low-voltage AC measurements, which is crucial for spotting stray voltage leaks in the aquarium. With pumps, heaters, and lights all running in a 300L tank, I've had that occasional "tingle" when reaching in with a small cut on my finger not good for both me or the fish Using this multimeter on the AC volts setting (usually the 200V range for sensitivity), I stick one probe in the water and the other to a known ground (like the screw on a outlet plate It picks up even small induced voltages from the equipment reliably letting me isolate issues by unplugging devices one by one. Last time it helped me pinpoint a slightly higher reading from an aging heater, which I replaced before it became a real problem. Readings are consistent and accurate enough for this kind of DIY use close enough to spot anything over a few volts that might stress the fish or risk a shock. It's not a high end so don't expect lab grade precision, but for the price it's fantastic value Battery life is good, auto-off saves power, and the data hold function is handy when you're juggling probes in wet conditions. If you're a DIYer with an aquarium this is an affordable essential for peace of mind Highly recommend it for general home electronics and tank safety checks! 5 stars from me
