## Customer Reviews

### ⭐⭐⭐⭐⭐ A Great Meter!
*by B***. on November 29, 2019*

I'm a huge fan of Dave Jones and his EEVBlog website and YouTube channels, and followed the development of this meter with a lot of interest and anticipation. The feature set in this meter was specifically designed by Dave to meet his requirements & desires for a reasonably priced meter that focused on electronics testing and troubleshooting. This was one of his pet projects, and the resulting meter is perhaps the best value for money in a mid-range meter. In fact, this meter does some things better than some much higher priced meters. Here's what I particularly like:- build quality is excellent- regular firmware updates that are easy to install- data logging to an internal SIM card or...- data logging via Bluetooth to a really slick Android or iPhone app- fast continuity latch times- very well done documentation that is updated with every firmware release (both the documentation and firmware updates are downloaded from Dave's EEVBlog website)- the meter has been tested and certified by Intertek (a UL equivalent), which means it actually meets its 600 volt CAT III protection rating- it measures temperature- the supplied test leads and thermocouple are high qualityAre there any negatives? One or two minor gripes. First, in the design phase Dave struggled to get the meter squeezed into the small form factor he prefers. I'd say this to Dave - don't be afraid of large meters! Embrace the big! The layout on this meter is somewhat cramped. Next, being red/green color blind like much of the world's male population I find the red secondary function markings on the dial hard to see - REAL hard to see. Dave, if you are thinking of changes to an upcoming production run of this meter I'd recommend changing the secondary function markings to something easier to see - perhaps yellow?At the end of the day all I can say is this is a great meter, particularly for the price. It sits on my bench and gets used almost daily for troubleshooting and kit building. Highly recommended.

### ⭐⭐⭐⭐⭐ Fantastic unit!
*by M***E on March 2, 2020*

I've watched EEVBlog for years now, and Dave Jones is more than just a Aussie voice on YouTube. He's a skilled electrical engineer, and this definitely shows. The bluetooth connection to your phone just works, with no hassles. It's well done, accurate, and really my only gripe is that it's a bit on the chunky side. However, since mostly what I'm doing is the oddball voltage check with a portable unit, it's entirely acceptable. It's not like I'm a field engineer who needs something small and portable.

### ⭐⭐ Test Leads Don't Have a Tip
*by M***D on September 24, 2019*

The meter seems nice enough. The test leads are worthless. They didn't come with tips. The came with the HV tip covers but not tips. It's not what I expected from a meter in this price range. Amazon has a bad habit of not checking their returns and not catching people stealing parts (or alternatively they know it's missing parts and don't care). I can't recommend this meter as good for anything but sensing temperature. The thermocouple seems to be functional. I didn't need a temperature gauge, I needed a meter.
