Great value and worked as expected

I recently had to replace a sprinkler control box which was hard wired into my house fuse panel. I purchased this multimeter to be sure I was safe working with that amount of electricity. I am happy to report that the job is done and I am still alive, so the multimeter worked as expected. The price was hard to beat and it felt like better quality than I was expecting. Happy with this purchase. Very easy to use. Read more

Effective and Affordable Multimeter - would recommend!

I grabbed this multimeter for some basic home and automotive troubleshooting, and it’s been surprisingly solid for the price. The readings are consistent, the display is clear, and switching between modes feels tactile and intuitive. It’s not a high-end professional tool, but for everyday electrical checks, battery testing, and DIY projects, it does exactly what it’s supposed to. Simple, accurate, and budget-friendly. Definitely worth it if you need a reliable multimeter without spending a ton. Love that it's not too heavy and it's compact size. Read more

Works for testing grounding mats, but cord length and instructions need improvement

I purchased this to test whether my grounding mat was actually working, and in terms of functionality, it does what it’s supposed to do. I was able to confirm that my mat is grounded. However, I ran into a few usability issues that are worth mentioning for anyone considering this, especially if you’re not familiar with electrical tools. The wires are not long enough to easily connect to the grounding port without lifting the device up. In my case, the outlet is positioned much higher than normal, which made it impossible to keep the tester flat on the bed while connected. Because of that, I couldn’t touch the mat properly while it was hanging between the outlet and the bed, which affected the measurement setup. To get a usable reading, I had to touch the mat with my foot instead, which worked, but wasn’t ideal. Another challenge was the instructions. They were not very beginner-friendly. I’m not an electrical tech person, so I had to watch YouTube videos and read online guides to fully understand how to use the tester correctly. Pros: Confirms whether a grounding mat is working Once set up correctly, it provides accurate results Useful tool for grounding verification Cons: Wires are too short for some outlet setups Difficult to use if outlets are positioned high Instructions are not clear for beginners Who this is best for: People who already have basic electrical knowledge or a standard, low outlet setup. Beginners may need additional guidance. Overall: The product works and serves its purpose, but longer cords and clearer instructions would greatly improve the experience especially for first-time users. Read more

THIS UNIT HAS EVERYTHING GOING FOR IT !!!!

Beautiful design, rubberized body very easy to hold and light weight. I found the ability to backlight the readings is the very best I have ever seen, this feature would sell me instantly. Would definitely purchase again and would highly recommend due to apparent quality and ease of use. One last note; the probes are very well made. For the surprisingly low price this is a fine unit.

A very good product.

A well constructed, easy to use piece of equipment at a very good price. This was a great replacement for my old analog multimeter and I'm very happy with this purchase. The 'hold' feature is particularly useful and the illuminated read-out is a real plus when working in poor lighting conditions. Read more
