Very Accurate and Convenient
I checked the readings against other watt meters and against power using devices with known wattages, and found the readings to be very accurate - possibly within 1 per cent. The meter gives real wattages and not just volt amperes in that it accurately corrects for inductive loads with low power factors. I tested loads with power factors between 0.35 and 1.0, and it gave consistently accurate results. Although the meter does not display the volt-ampere and power factor reading, you can easily get it by multiplying the volts by amps, and then dividing watts by volt-amperes to get power factor. I was at first skeptical about how accurate the clamp-on current transformer coil would be compared to regular current coils, but found it to be just as accurate, and much more convenient in that you do not have to disconnect and reconnect circuit breaker wires in distribution boxes to get the current transformer coil on it. Depending on your application and testing usage, it may be useful to solder on additional wire lengths and test clips for easier connections.Verified purchase: YesCondition: New

Not Split CT's, thus not good.
I really don't like the CT's (current transformers) are not the "split type" so the system has to be de-energized, and wiring disconnected in order to install the CT's to sample current flow. It's because of this that I do not think these are a good value. For instance, there is a major problem if you want to measure the total entrance current to a dwelling. It would require lifting the incoming electrical supply and you would need to remove the electric company,s meter which get you in trouble. Split CT's are the only way to go in any case and they are much easier to t=replace if they become defective. JKVerified purchase: YesCondition: New

These things are great!
I have these installed on a few different projects and I love them. They are surprisingly accurate. I compared them to a kill-a-watt and the readings were within one watt of each other. The KWH feature is nice for tracking consumption and it has a blue backlight that can be disabled. This one has a nice design so that you don't have to disconnect any wires to install it. Very handy product!Verified purchase: YesCondition: New

Nice little panel mount power meter
Works well if you want to track your power consumption separately from your company meter. Takes a little ingenuity if your main panel needs the cutout. If you're halfway skilled at using a dremel cut off wheel it's easy to do. I don't think it's as accurate as say a $300 fluke but it's not that inaccurate. It's good enough to find a discrepancy and warrant the use of a NIST certified device, which is needed for court cases. This little guy is even smart enough to measure power factor and distinguish between true resistive loads and loads with power factors. It doesn't flat out display the power factor but it is evident in the power measured at device, if you do the math.

Great package for a cheap price
My only complaint would be that the tabs on the back of the screen are light and easy to break off while trying to fit in a metal enclosure. Other than that the screen is clear and very easy to read. Not overly bright but visible from any angle with bright florescent lighting all around. Quality is great, bought 22 of them and not a problem with a single unit.Verified purchase: YesCondition: New

Great little device.
I have bought 4 of these devices from different dealers, but same model. It is so nice to be able to read Voltage, Current and power without having to do the math. I have used one for a portable test meter and everyone wants to borrow it. Get item. Very accurate. Would recommend to anyone wanting to know the info it gives you..Verified purchase: YesCondition: New

Good compact form and function -
Good compact digital watt / volt ammeter. The function button is slightly recessed which necessitates the use of a toothpick or similar to activate. The mounting clips keep the meter in place but the plate you mount it through works better if thin. The readout is clear and sufficiently large enough to read at some distance.Verified purchase: YesCondition: New

I like it
With this little toy i was able to trace every problem area in the house. I am replacing all lights in the house with LED light bulbs because current once are drawing allot of power. I had no idea how much more efficient LED's are until i tried this device.Verified purchase: YesCondition: New

Great product and price, and works well.
Functions as advertised. I was a little confused from advertisement as "open close CT". However, picture clearly showed a closed CT, that would work for my application.Verified purchase: YesCondition: New

Measures small loads well
I bought this to monitor a load on a local circuit for a client of mine. It was recommended to me by a friend. When I received it, it looked like the best way to mount it was in the cover of a 4 11/16 inch junction box. It fits very nicely there and looks good as well. There was still room inside the box for a current transformer and a 1/2 amp fuse in an inline holder. I have tried some small loads on this meter and it measures low power usage fairly accurately. This is a good test of a watthour meter. About the only thing I don't like about this unit is the lack of a power factor measurement.
