I am very satisfied with the overall experience. The seller was incredibly professional, polite, and helpful during our communication. The product was shipped very fast and arrived in perfect condition with safe packaging. As for the device itself, the ATR-FSM has a very clear, bright screen and a user-friendly menu that is easy to navigate. The battery management functions are great, and the 3DP casing is lightweight and pocket-sized. It is a nice, handy little gadget for basic 433 MHz signal testing and hobbyist use. Five stars for the top-notch customer support and smooth transaction!
