Review on Tekpower TP4000ZC Auto Ranging DMM with USB Interface - PC Based Digital Multimeter, Similar to MS8220R, Computer Compatible by Chris Tisdale

Worked fine for a few years (bought in 2014). The internal fuse had just blown and I decided to just replace the entire meter with something else. The sound disappeared on this device in less than a month of ownership - only a couple of times. I immediately contacted the manufacturer about this and they seemed to address my concerns, but at the time I didn't think it would make sense to ship the device to them as requested, so I simply declined. Now I know that Revane would probably have turned his back on me, but still I wasn't 100% satisfied with the answer. Auto selection is a handy feature. The probes are not very good; They seem pretty cheap compared to other gauges I've used, especially in the area where they connect to the gauge's terminals. In general, I am satisfied with the device, but I decided to switch to something else.
