Light Switch & Tasmotizer

Hello

I have two questions:

1.) Can someone please recommend a single poll light switch that they’ve recently purchased and flashed using Tasmotizer?

2.) Can more devices be flashed using Tasmotizer directly connected to a device, rather than trying to upload Tasmota OTA using Tuya Convert? Recently I’ve had difficulties flash a device OTA and I thought about switching to Tasmotizer.

Thanks in advance for any help that can be provided.
