      Works great and can be tossed in the glovebox without being out a lot of money.

      compact pocket multimeter

      Overall: 5 out of 5

      This is a great little meter! It seems to be as accurate as the high dollar Fluke meter that I use on my job. It's small, (about the size of a pack of cigarettes.) It's accurate, and seems to be reliable, although, I haven't had it long. But at this price, it's a no brainer. It uses a small cylindrical shaped 12v battery that comes with it. I don't know how you could go wrong with this.

      Very Handy

      Overall: 4.5 out of 5

      I purchased 2 of these little units a year ago and was surprised at its accuracy. I was worried the rotary switch was going to be cheap, but It is a good build quality. Only 2 downsides: 1. The leads are soldered in and not plug in so you will have to replace with the same type. 2. Don't leave the unit powered on as there is no auto shut off. Overall: I wouldn't hesitste to buy this meter again. It's a great value.

      A bit flimsy in the construction, but hey... this meter is practically free. Keep the clamshell package to protect meter while in the toolbox and you will be fine. It works great and is suprisingly accurate. Definately worth buying several to have around when you need a quick measurement.

      Simple, Convenient, Accurate

      Overall: 4.5 out of 5

      This little DMM is perfect for the "on the go" technician or handy man. I bought one of these a while back and have not been disappointed. It is perfect to throw in your back pocket or glove box and is durable and accurate. Since it is so cheap, I have bought a couple and keep them in different locations for emergency use. Highly recommend!
