Amazing value! Easy to work this clamp meter and seems to be plenty accurate! I love that it reads DC amps as well for testing motors and air conditioner pumps.

I am not an easy person to impress.  The value of this radio equipment is extremely impressive!  I am new to Ham radio and I took a chance on this radio as a possibility for field communications in the event of an emergency!  This radio is way better built than I expected for the money!  It gives me the communications that I was looking for.  It gives me the ability to monitor emergency services. It gives me the ability to monitor weather conditions.  It is what I would call an outstanding value for the purchase price!

Now for the negative:  No it's not as well made as a Yaesu handheld!  Yes, it's difficult to program manually!  But the Yaesu handheld I purchased was almost $200 while this radio is $30.  Both radios do what they are made for.  If you are like me and just getting started with Ham radio then you are most likely wondering about range of communications!  With this radio in a relatively flat landscape with intermittent foliage you can easily communicate for two miles.  In an automobile with an external auto antennae I was hitting repeaters 15 miles away.  In the house with a roll up slim Jim antennae (located inside the house)  I was hitting repeaters 15-20 miles away which gave me communication ranges of thirty miles. 15 to the repeater and 15 from the repeater.  I also want to,put a plug in for the slim jim roll up antennae. I am amazed that a $30 portable antennae can provide uhf and vhf reception within the house ( mountain stone exterior).  Yes, it is located inside next to a window but wow, no external antennae needed!

I bought the M105 because I wanted an analog meter to tune the output circuit of a Part 15 AM radio transmitter and needed to adjust for a peak of the voltage reading. It's surprisingly hard to perceive the peak or null in a measurement using a digital meter.

With the M105 the tuning was a snap as the peak voltage is easily spotted on the large (for the units size) meter face. I was impressed with the quality of the meter, it fits well in my hand, is light enough to carry in a backpack(something I do at radio swap meets), and has the right balance of useful features. This does not feel like a $10 meter!

I would recommend this for anybody looking for a fairly rugged, compact, and lightweight analog meter.

It is a very impressive little meter. It has a solid feel and weight with a rubber feeling along the sides of the meter.
It also has a better ohms and capacitance range than my Fluke 902.
The fact that it easily fits into my shirt pocket will add great value to this product since a meter in my pocket is better than one in the truck.
I have used it to measure non contact voltage, capacitance, Ohms, AC voltage and AC amperage in the 2 days that I have had it.

The cons to this product:
The dial doesn't have as solid a feeling as my Klein CL2300 or Fluke 902 (but those meters cost many times the price).
I wish that it could measure micro amps DC for testing flame rectification.

Solid performer right here! I do a lot of electronics prototyping and such on a fairly regular basis. I am always in the need for a specific power supply that will match requirements of my project. Rather than having to have a bunch of different fixed voltage regulators, I've discovered the regulators from DROK that easily let me adjust the output voltage and amperage to match my needs. The LED displays on the board (which show voltage and amperage) let you show either the input or output parameters. I've performed multiple tests with my multimeter at various settings to ensure the accuracy of the board and the displays. Each time I was pleasantly surprised to see how accurate this unit was. It's fairly compact too, so it'll fit into the enclosures I'm using. I couldn't be happier and I know I'll continue to order more in the future. Thank you!

I think this is the answer to an RV owners prayers. When you have a low tire, finding a place to except your RV AND having a compressor large enough to pump up a tire to 100 pounds is sometimes not quick to find. Or waiting an hour or more for your road service to come. When I received this, I let about 20 pounds of air out of a tire and this compressor pumped it back to 80 pounds in less than 2 minutes. I feel better now knowing that in my travels I have an air compressor on board. Chances of needing are usually slim, but if I do it may save me hundreds of dollar in damage or wait time. The only issue may be the  distance the compressor cord and hose will be from reaching your low tire. If that will be a problem, you can use some jumper cables or make an extension cable with some 10-12 gauge wire or you can buy and extension hose, but the extension hose is very over priced.

While most reasonably priced clamp meters only measure AC, I found this meter to be just what I needed to be able to check the operation of alternators and battery chargers while working on my car and camper.  It has a good feel to the quality of the plastic and operation of the clamp, it's no Fluke, but it doesn't cost $250 either.

To check the accuracy, I took it to work to compare it to the calibrated systems that use precision shunts to measure current.  While measuring 380.2 DCA on the precision shunt, the meter measured 379 DCA, giving a far better accuracy than I need. If it holds up as well as I think it will, it will be a Great value for the money.

Was looking to purchase an incline manometer for reading low differential pressures on sensitive air switches.  The price for this was a bit more than a manometer and I am so happy I purchased this test meter instead!!  No fussing to get a manometer set up, find a place to hang one, etc. when working on equipment.  The meter price was less than many and more than some, but based on the reviews I purchased it and have been completely satisfied.  This has saved so much time and hassle it has already "paid for itself" easily.

This meter is really a FULL featured multimeter sporting a large clamp. It has high end features like hold, peak and true RMS measurement, among others. Most importantly for me at least, the 369B is tough and does a fine job with D.C.current clamping. So, no sweat with automotive work, among other applications.  This meter is very versatile, heavy for size, and built with quality guts...for the sub two bill price. I was not disappointed in any category. B+K also has a super Customer Service Department, a valuable rarity nowadays. Awesome.

I was debating whether to buy a different more expensive engine monitor but talking to a number of RV diesel owners was convinced that this would give me the best bang for the buck.  Main reason i purchased was to monitor engine and transmission fluid tempature.  Suspected that the gauges on my coach were giving me false readings.  Hooked up the ScanGauge and within an hour knew that my gauges were off by as much as 20 degrees F.  In addition, this gauge gives you instant and average mpg.  It helped me to be a better fuel conscious driver.  Prior to the installing the gauge, I would run with traffic and averaged 6.0mpg, with the gauge monitoring the instant and average MPG I was able to determine the best fuel enconomy speed was 62 mph.  Maintaining that speed my average fuel consumption went up to 7.6MPG.  If this continues, and I haven't any reason at this time to think otherwise this gauge will soon pay for itself.

This worked great! I work on motorcycles often so being able to point this at the header pipes and find out which pipe isn't running as warm as the others is an unbelievable amount of help! This thing has helped me diagnose poor A/F ratios, misfires, vacuum leaks, etc.

The price was great and the LCD screen is clear and easy to read even at night. The laser beam also works well even in direct sunlight.

My only real con is I wished that it was rechargeable, but it does come with a battery so because of that I will not dock a star. I've seen this item as cheap as $15, but I paid $20. I would happily pay $20 again for this beyond useful tool.

My existing VDO meter was reading low voltage so I first assumed it was the alternator. I put a test meter on the input wires to the voltage meter were yielding 14.2 volts and the meter was reading 12 volts.
Check the simplest thing first right?

Forty ($40) delivered to my door in three days.(thanks Amazon)
The new meter has a threaded body and a large plastic sleeve/nut that holds it in the dash.
Much easier installation than the old clamp method.

The new meter reads the same as the input wires read..... problem fixed.
I do have an issue with VDO manufacturer? why did the old one go out of calibration??
Why is there not a rheostat adjustment to calibrate the meter?( so you are forced to purchase a new one?
I had to purchase VDO replacement to match the other gauges in my Dash
I am satisfied with the product, the cost and the delivery

I would give more stars if I could!  Great product for home and RV!

This all in one meter is awesome, it can tell you the readings of PH, ORP (oxidation-reduction potential), TDS (total dissolved solids), EC (electric conductivity), as well as the temperature of the water. This is a must for anyone with an aquarium or anyone who wants to test the quality of their water. After calibrated correctly, the meter works very well compared to the saltwater specialiyy store I shopped at, I compared the readings of pH, ORP and conductivity with my old meter (Milwaukee), the readings are very accurate and easy to operate. Highly recommend!

As a computer engineer this has been absolutely fantastic. The auto-ranging has worked like a charm, I've had some other meters in the past that had odd scaling.

Very nice meter. I am using it in industrial setting and it beats a Fluke on price and usability. The probes are better than expected and the flashlight is actually usable. Bought a cheapo clip magnet for the strap. The Hz readout will detect 60 Hz without contact. Would not rely on that as a Voltage detector. Checked the RMS readings vs. a "calibrated", traceable meter and it matched.

Great meter Really good price.  I highly recommend!  After I wrote this first review And apron attempt to actually use them.  They will not calibrate so in my opinion they look and feel very impressive however looks are and were deceiving.  I hope this helps the next buyer
