Question about KingSmith Treadmill WalkingPad A1

I have read that the S1 is the successor to the A1. But I don't quite trust the statement yet. Xiaomi does not have the S1 on its website (Google search for: KingSmith Walking Pad comparsion). I have only seen the S1 in a single test on YouTube. Moreover, it is almost unavailable anywhere and originates from a crowdfunding site (Indigogo). I suspect that the S1 = the A1 Pro. It may have been renamed for marketing in the EU. The P1 doesn't exist in the EU / CH either. If you search for comparisons between the pads, you will mostly find A1 Pro vs. R1 Pro. Maybe the Digitec/Galaxus product team can help?

Hello, The difference is the letter :-) I can't tell you because I don't own both devices. Greetings
