If you are new to VNAs, this is an excellent tool to learn to interpret the results on a Smith chart.If you're looking to buy, or have bought a Nano VNA or similar I highly recommend this.The only downside is that the U.FL connectors used have a very finite lifetime. Too many connection cycles and they will wear out. Still for the cost it's hard to beat! Remember to calibrate your VNA before measuring, using the open, short, and load on the board, and the cables you will be using. If you calibrate at the ports of the VNA the results will be wrong when you measure through cables, because of the phase shift introduced by the cables.It's really inexpensive, you might just buy two!

The board arrived on time and is of good quality. The price was also much lower than similar items sold on eBay.The reason for only 4 stars is the quality of the connectors installed on the board, but that is a design issue.Thank you!
