I'm a big fan of the high-end Flukes so I've worked with the best. Well, these defintitely aren't the best, but you can't beat what you get for the price. I got it for my brother for his car and it does the job well.

First, the bad:
1. No auto shut-off. You gotta make sure you turn it off or the battery will just keep draining away.
2. No auto-sensing. You gotta set the dial for the range you're looking for. But hey, I like it so much I don't care that I can't be so lazy.

And the good:
1. All the features. You get all the standards PLUS a tach and a dwell-meter! That'll about cover your carbureted cars.
2. Price. You can find multimeters that can't do the extras for the same price and even more. Great bargain.
3. Alligator clips. Simple things but it'd be a pain without them.

Plus, this thing will handle all the home electrical work.

As for the rest: I won't vouch for its durability but Actron is a decent company. They go towards affordable but not junky. The case is made of a light plastic, but it doesn't seem fragile. As for the tolerances, they're not bad:
DC Volts
Range: 200mV, 2V, 20V, 200V
Accuracy : ±(0.5% rdg + 5 dgts)
Range: 1000V
Accuracy: ±(0.8% rdg + 5 dgts)

AC Volts
Range: 2V, 20V, 200V
Accuracy : ±(0.8% rdg + 5 dgts)
Range: 750V
Accuracy: ±(1.0% rdg + 4 dgts)

DC Current
Range: 200mA
Accuracy: ±(0.8% rdg + 5 dgts)
Range: 10A
Accuracy: ±(1.2% rdg + 5 dgts)

Resistance

Audible Continuity
Buzzer sounds at approximately less
than 30-50 Ohms.

So for the price, a good deal.

This multimeter is an all around good tool. It has all the features you need plus some of the features that only the more expensive ones have. Like the battery tester and backlight display. I am studying electronics right now and I find myself getting a ton more use out of it than I thought I would. It is easy to use and the instruction manual that comes with it tells you how to perform most common tests that it does with pictures to go along. There are comperable multi-meters out there that cost less but most would cost more. There are certainly better multi-meters than this one but they will cost more. The only bad things I can say about this tool is that the battery is hard to get to. You have to remove 2 screws in the back and pry it apart. Actron should have just put one of those slide off battery covers on it. Also most multi-meters come with some sort of rubber, protective sleeve, that also has a lanyard for your hand so you dont drop it. If this mult-meter had a lanyard and the battery was easier to get out, I would have given it a 5 Stars.

This will perform any test a neophyte electrician will do. The instruction manual is well written and understandable. Instructions provided for most ignition tests of classic cars and sensor testing of newer cars.

I had been eyeing this multimeter for a while, and when it went on sale for half its list price, I grabbed it. It arrived promptly and works very well. The unit has a solid feel to it and the blue rubberized case around it and the "stand" behind are good features to have when working around places where it might get bumped like in the engine compartment. I found the included alligator clips a useful bonus - a lot many of the ones in the mid thirties price range don't have this.
Two minor flaws - it needs a 9 volt battery and doesn't ship with one. That was a minor annoyance - not many people have these just lying around the house. Why not design the meter using AA batteries or just ship it with a 9V battery?
Second is that there is no sticky film protecting the (rather large) LCD display. For a meter that is meant for harsh outdoor environments in which it might get scratched, this is definitely an oversight.
But overall I am pleased with my purchase and would definitely recommend it as a solid entry level multimeter.

My requirement is a hand held engine analyzer for ignition points
on a motorcycle engine. This tester meets all my requirements
for tuning a motorcycle engine and trouble shooting.
I recommend this instrument highly.

bought for tachometer use
harbor freight version: take reading, multiply by 50 & divide by number of cylinders, i'm not joking! (had to call them this isn't in the manual) and it has a selector for cylinders.
actron version: multiply reading by 10
also includes manual on how to troubleshoot engine sensors. has been very helpful.
highly recommended for any shadetree mechanic!

I bought this to chase down a short in my truck. I got really lucky and found it in about ten minutes. I spent about a half hour fixing the short, then about 2 hours playing with this meter - it'll tell you all kinds of things. If you're going to be a DIYer with your vehicle, one of these meters is a must. Do your research on prices first though. I found one at a car parts store for a few bucks less.

I bought this 6 weeks ago and used the continuity tester to check some wiring in my resuscitation of a dead car. It works great. Now that the mechanical parts are done I went to use the Ohmeter. It doesn't work. Neither does the DC Voltmeter. The Continuity tester still works great! I only used one function on this piece of crap once. Buy any other brand.

Great item, service and price, it will be a valuable tool in my tool box

I has a lot of options, i comes with a very well explained manual with photos of about anything you can do in your car (and it's a lot of tests) and with this cocodrile clips, a has to be tool if you are in the do it yourself clan, reminder! doesn't measure any AC voltage or amps, only DC
