Rated 4 out of 5 by Excellent Value This MultiMeter is a great middle of the road unit for the average user. I personally would not buy a cheaper model, you need a good unit when it comes time to use it.When you need a multimeter you want one thats going to work and be accurate when it comes time to break it out to use it. To me this is a homeowner model, not any of the cheaper units. I would recommend to any casual user. If you are using a multimeter every day I feel a much higher end unit is nessasary June 11, 2014
Rated 4 out of 5 by To Replace the Battery This product does what it is supposed to. To replace the battery, you have to slip the multimeter out of its green sleeve. Then, you will see the two screws on the back of it. August 15, 2012
Rated 4 out of 5 by This meter is FINE for the price it cost. This DMM is fine for the price, you get what you pay. It is not the best multimeter or most accurate one but it does what it is suppose to do. Cannot compare it to a "Fluke" because it is not a Fluke. Most people who have negative comments do not know much about electricity/electronics and have little experience with a multimeter. All multimeters function about the same. One user complain about the fuse blew when measuring the voltage on a circuit breaker. The fuse that was described is for current protection, the probes must have been connected to the wrong connectors. Another describe measuring the battery strength. You cannot measure a battery's current directly, that is a no no! The measurement is meaningless because this is the same as shorting the battery. You need to connect a load to the battery and measure the current. The most common complain was about the battery; remove the sleeve and unscrew the back cover. YES, some of the marking is terribly colored so it is difficult for older people to read. Oh yeah, the manual; it is not well written but any manual (well written or not) will not teach you how to make measurements. It will tell you what the markings are for and what to do with it but it will never teach you how to make a measurement. Anyhow, the nay sayer don't know what they are saying. It is fine for what is cost. If you want better accuracy, get a Fluke. May 10, 2014
Rated 2 out of 5 by Look for a multi-meter with better dial labelings It is impossible to read volts, ohms, etc on the meter dial. The gray colored unit camoflages the green and red labeling of the voltage, resistance, continuity, current etc. This multi-meter comes with standard probes. It would be helpful if alligator or crocodile clips were available. The display has a digital readout but it would be nice if it had a back ground light. In continuity: if you touch the probes together the meter does not beep-- other meters come with sounds. The meter comes with a case cover which has a stand for for table use -- a nice feature.

Rated 1 out of 5 by DO NOT BUY THIS DEVICE ! I use a digital meter to check my wide range of batteries because I want to see a 1.5 volt common household battery show 4.0 milliamps (a common 9 volt battery should show 25 milliamps).This many milliamps or more are required for electronics, while flashlights can work if dimly at much lower numbers. This device is difficult or impossible to use for this or other purposes. There are many problems: 1) The 7-page "manual" is not only difficult to read but is worthless.The illustration of the front side of the device measures a little larger than 1" to 1/2" and so requires a magnifying glass (not just reading glasses) to see clearly. There are no examples, including the most common uses such as batteries and house-current. The 3 sentences at the bottom of page 6 about installing the battery are hard to find, even though this is the first thing everyone must do, and one instruction is foolish ("be careful to observe battery polarity" when you are using the supplied 9-volt battery - how could you attach the leads incorrectly?) 2) Key markings around the dial are in dark green against a dark gray cover, and so are almost impossible to read even in good light and using reading glasses. The attached photo doesn't show this because I optimized it using Photoshop to make it much clearer than in real life. 3) Most importantly, it doesn't work well. I measured brand-new D-cell and 9-volt batteries, and no setting measured anywhere nearly the correct current (and thus battery strength) of either (note I used a neighbor's multimeter and found they were actually a bit over these minimums). It is therefore useless for even doing the most trivial measurements. May 23, 2012
