Received in good condition in the black cardboard box that is generally seen with these, 2 x pigtails, open, closed and 50 ohm load etc. Casing is plastic but pretty good quality I think and is light weight and sturdy. 4" screen and larger is a must. I am glad I did not go for the 2.8" version. Battery life is pretty decent. As a radio ham I purchased it to replace my SARK for SWR and to play with filters and for building and testing VHF/UHF antenna. So far I am extremely impressed with this unit's performance after calibration. It is no commercial VNA but for my use it is perfect and any HAM's use it should be perfect. Filters built using software and then tested on the bench with this unit have produced the same results as the software emulation. Checking crystals for matching works well too. Tested various antenna I have from a slimjims to multi band yagi and some dipoles that are in use and were setup with a commercial meter and result are the same, very happy with this VNA. Downloaded software for my android phone and used the cable length test, very accurate. Think it is excellent value for money and the better of the units available from Banggood especially if you are going to use it outside for antenna tuning, then a unit in a plastic or metal case is a must. The only unit I would maybe consider as the next purchase is the 50KHz-3GHz 4 Inch Display Antenna Analyzer SAA-2N from Banggood.
