Upgraded ATS MINI V4B Pocket Radio SI4732 DSP Mini Radio Receiver with ESP32-S3, EMI Shielding Cover & ESD Protection, 1.9" IPS Color Display, Hi-Z Amplifier & 1W Speaker for Travel Radio Enthusiasts

Thanks! On AM and FM the digital tuners I have really suck. They only see the strongest stations. Or is it just that my cheap radios have cheap digital tuners? I see an "Upgraded ATS MINI V4B" at https://www.amazon.com/dp/B0GFS7JDMP I see four models. Are the metal cases better shielded? And is it just me, or do I see two slightly different sizes?
