Due to wish-list confusion, I got two moisture meters for Christmas. I solicit opinions about which one I should keep. One is a Sonin Model 50211; there is a cord between the meter itself (black with an analog needle display) and the probes. The other is a JT-2G; there does not seem to be an actual brand-name (which seems odd) and the thing is grey plastic with a digital readout and yellow buttons and a yellow cover on the probes. Thanks !
