Re: DVM on sale at Harbor Freight $3.99
They do work just fine for the most part. I have several, however, I have found them woefully inaccurate when attempting to measure resistance to any degree of precision. Part of the problem is the probes oxidize over time, and the leads do not plug into the meter terribly well. For $4 (I actually got a few free), I can't complain though. They're good for class projects and to throw in a travel box or bag. But, I still keep a quality meter around when needing to measure resistance.
