Review on 📻 Enhance Walkie Talkie Performance with Gam3Gear Surecom SA 160 0.5-60MHz Colour Graphic Antenna Analyzer for Radio Testing by David Dortch

An example of poor engineering is here. The rotary selector doesn't have an effective debounce circuit, so scrolling through the menus is really annoying. I've seen this complaint from others and I've seen it on more than one device. I even replaced the rotary encoder with a higher quality device and it didn't matter. This is a code issue. The user interface is not great. Simple changes like frequency range or center frequency are unintuitive and the awful instructions are almost unreadable. However, it gets the job done and I've used it to tune the antennas. In addition, it is compact and cheap, so the price-performance ratio is enough for the purchase.
