My one minor complaint is that the tips on the two probes that come with this multimeter are not super "sensitive". I don't know if that is the right word, but sometimes it seems like you have to touch the very tip of the probe to the contact you want it to have. This is good for testing precise things, but sometimes is disadvantageous if you at trying to test power connectors.
Furthermore, the kick stand helps props the DMM when trying to get readings in tight spaces or very flat areas. The probes do feel cheap & I question their accuracy sometimes but at this price point, can't complain. The do NOT hold into the side holders but I use velcro to wrap the wires to the DMM when not in use so it doesn't bother me.
Overall great DMM for the price
The multimeter functions picked by spinning the dial seem to work properly. I’ve mostly used it to determine voltage on 12 volt batteries. The probes/leads are high quality, with what appears to be durable wiring. Time will tell. The unit itself is constructed with rubber bumpers to protect the plastic housing. Overall, it appears to have been built with durability in mind.
There are a few quirks that I’ve noticed with this, theyre not deal breakers, but certainly shouldn’t occur on a new product. First, the indicator lights initially worked, but after a few weeks they stopped functioning. The multi meter still functions properly, but the indicator lights don’t. There are other reviews that state this as well. Second, the batteries that power the unit are a pain in the neck to get to. Why not just make it an easy access cover?
If the Manufacturer would fix the indicator light issue and revamp the battery access cover, this would be a 5-star product.
1. Case Missing - just a PIA to have a wad of probes/wires just sitting there.
2. Poor Probe Connectivity - a simple Continuity Test using only the Probes provides a disappointing experience. Multimeters that I've had for 30 years produce a very clear audible sound when touching the probes against one another. Not this unit. You have to "scrape" the probes together to get a good enough connection to hear an audible sound indicating no resistance.
Otherwise, it does the job and the wrist/forearm strap can be somewhat useful. It just is not as refined as other competitors. Fix the two annoyances and you have a near 5 star product.
UPDATE: the battery testing feature has stopped working. Reason: an internal fuse blew. The cost of a fuse replacement is 1/3 the cost of a new unit. Consider finding a thin copper wire and span it across the fuse to rejuvenate this feature. That's what I did and it has operated fine since. There is a risk of frying the unit, but, for $17 it's worth the risk to me. I suspect the original fuse was undersized. Search YouTube for this model and someone demonstrates how to fix the fuse.
Auto-range function is really helpful, and works well.
Beep for continuity test is way to soft to be useful if background noise is present, say with a running engine or fan motor.
Plastic tabs on the case are laughably bad. Don't expect the probes to stay in them like the picture shows, not even the slightest bit grippy.
Final note, this is an Equus sub-branded product. For those who haven't had the pleasure, Equus is notable for cheap, crummy diagnostic tools in past years. I've owned a few in my life, and have discarded them quickly as they failed. Dwell/multimeters, timing lights, tachs, etc. All have failed after what I think is very limited casual use. I usually pick one up for cheap somewhere because I need something quick and that's what is there. About Harbor Freight quality, if that makes sense.
So, Innova is generally decent quality for consumer-grade tools, but seeing Equus under the display (which would have warned me off if I'd seen it earlier) makes me think I'll be buying a replacement at some point.
I've already dropped it once or twice and it has held up really well. I've gotten plenty of use out of it and would recommend it to someone who is looking for a good meter, with lots of helpful features for a pretty good price.
