   As others have said, it worked for a while but is now erratic and the ohm meter is dead. Save your money. Don’t buy this one.

   The item worked out of the box, as I tested it and put it aside for later use. In 3 days, when I needed it, it didn’t work.

   I’m an electrical engineer and fixing up these things is what I’m good at, so I opened it up and realized that the design is quite poor. The PCB that holds the wire connector is connected to the main PCB only through 3 solder junctions! This is ridiculous, everyone knows solder itself is brittle and can easily break. So what happens is that if you push the wire connector too much, it will transfer the force to the first PCB, and since it is only connected to the chassis and the second PCB through three solder junctions, one of them will break!

   Well I patched it up and made it work again, but I don’t expect the majority of people trying to fix this thing. Once fixed, it worked like a regular multimeter.

   Be warned!

   Yes, I know it’s very cheap but I’ve gotten much better results from other sub $10 multimeters – including the $4.99 “Trisonic” I found at the dollar store.

   First, right out of the box the display is incomplete as some digits are missing segments. Looking inside once sees the display panel is coupled to the main circuit board by a commonly used conducting strip. The circuit board and display are sandwiched together, held only at the far ends by screws. If you push down on the middle of the strip the display works properly. There is a plastic post on the back lid which is supposed to do that same pushing when the case is closed, but it doesn’t push quite enough. So I placed 3 layers of electrical tape on the circuit board where this post makes contact, and now the display is readable when you close the cover.

   I only bought this meter to have an extra “sanity check” in another location to double check unprotected lithium-ion cells for over-discharge prior to placing them on the charger (discharged below 2.75 volts or so they can explode when recharged). My first measurement was a pair of 10440 (AAA-sized) unprotected cells – and I turned white when the meter said ~1.15V on both of them. Close call? No. I took the cells with me to a location where I had a “known good” meter and (sigh) they read 3.98V. That’s more like it. Now … after that try-out, how can I ever trust this thing for anything that matters?

   This multimeter performs the basic functions OK but does not have a simple continuity check. A continuity check is one of the main reasons I bought the unit so I rate it 1 star.

   I have used this product before and needed a new one and Amazon’s price was right and saved me a trip to the store. It arrived very quickly and in excellent shape.
