Attention to details not there
For an instrument of this cost, I expect a well-written manual. This doesn't have it. While I can tolerate poor manuals, if I can figure out the relatively complex instrument, I have even less of a stomach for mis-prints and grammar mistakes on the front panel.I am referring to the "frequency" button which is printed as "freg", with a gee, not a q. Ouch. That single mistake makes the product difficult to keep. You can see the mis-print even in the Amazon product photos. eff are eee GEE. Yikes.The first functional problem was measuring a capacitor. It worked OK but was off by about 0.75 picofarads whilst measuring a 1.5 pf capacitor, even though the stated accuracy is a fraction of a percent. I figured out how to do a calibration, and then it worked better, but I was starting to lose functional trust in the unit.So I tried a 100 nano-henry inductor, that's a standard value for a project that I'm working on. The unit couldn't determine any inductance on the part under test. I thought that was within the range of the unit, checking the manual and the website (see the image I took). Should have worked.So I tried a second inductor.... no joy, didn't work either. Am I doing something wrong? It was seeing my inductors as a dead short, occasionally a little but of sputtering inductivity on the meter.At that point, the irritation of a bad manual and a mis-printed button on the unit came over me. This one's going back, and I'm ordering another LCR tester.

Something loose in the case
There was something relatively heavy and loose inside the case. No damage was visible on either the outer or inner box. The unit powered up, but I made no measurements and I decided to return it not knowing if there would be a problem down the road.I decided I better not buy another of this brand as it might be a design issue. I don't see any other brands available on Amazon.
