This is a serious high performance instrument worth 10 stars, but has a few issues that subsequent firmware upgrades should address. Most important problem that needs repair is assembly of PCB & screen into steel case. Upon receipt of unit found USB-C socket loose and charging plug on 15 degree down angle when connected. Removed case back, released white RTV securing LED lens and carefully remove PCB & screen to find USB-C attached by power & data pins only. Caused by case holes not punched in correct location and PCB & screen forced into position during assembly. Re-seated USB-C socket and soldered mount pins. Carefully scratch PCB coating beside USB-C to reveal copper then reinforce socket with more solder both sides. Do NOT disturb small tracks on power switch side of USB-C. Do same for USB-A socket. Use small file to enlarge USB-C and power switch holes in case, larger toward front, approx 1.5mm. USB-A not required enlargement on mine. Test fit to confirm clearance and when complete, clean filings, sharp edges & small amount of black paint with artist brush to protect. If you do not do this work, in short time USB-C socket will rip small tracks off PCB that cannot be repaired, rendering instrument useless. Don't over-tighten 6 PCB & screen securing screws as this can bend display. Can be overcome by confirming case face is flat by using edge of a ruler. Carefully tweak case so face is flat and level, which will straighten the 2 centre stand-offs allowing PCB & screen to seat flat. Once assembled, LED lens may rise slightly above PCB, simply apply small amount RTV to secure. Do not over tighten the SMA to N-socket nuts during re-assembly.
