Tools and Hardware Reviews of Palm-Size Handheld Digital Multimeter - DT830B
Customer Review: flimsy prodect
Summary: 2 Stars
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!
Customer Review: No auto-off
Summary: 3 Stars
I got this multitester through Amazon a few years ago at a great price, about $7. I use it occasionally for minor tasks like checking batteries and testing continuity. So as to whether it's accurate or not, I will defer to other reviewers. After a few years, the product still seems to work OK for my purposes. The big problem for me is that there's no auto-off. I don't know anyone who is going to remember to turn a device like this off every time, despite the best of intentions. So whatever you save in purchase price may be lost several times over in the cost of installing new batteries. It takes one 9-volt battery -- those rectangularish ones -- the alkaline versions of which can cost $5 or $6 apiece. If you get this multitester, I would use only rechargeable or inexpensive non-alkaline batteries.Customer Review: Mini Multimeter

Palm Size Digital Multimeter Tool, DT830B
They say you get what you pay for! Well, after taking the back off of this unit, I was surprised to find it reasonably well constructed on the inside. Solder connections are good and internal components seem well laid out.
My only complaints are as follows: cheap 9v. battery included, and, unlike the manual says, there is no audible ohms check.
Hey, for 6 bucks, how could you go wrong for a throw in your toolbox meter?
Customer Review: One Flaw
Summary: 3 Stars
I have been using this meter for a month now. As far as a volt meter,continuity checker and ohms meter I consider this to be well worth the price paid. It's only flaw and the reason I purchased this one is the transistor hfe meter, I have placed about 8 pnp transistors in the input and did not get any response until I placed a thumb on the transistor and applied some pressure, not knowing its internal design that method gives me concern for the long term durability of that aspect of the meter.
Customer Review: Disposable convenience
Summary: 3 Stars
As others have said, good for the price but keep your expectations reasonable. I carry it in our racing trailer so I won't be upset if it gets lost or broken, but didn't realize that to change the batteries you need to have a mini Philips screwdriver (jeweler size, which I didn't have). So waited till I got home and then broke one of the cheap Chinese screws trying to get it out. But still works OK with one less screw holding it in....
