What are the differences between this “upgraded” model an the orginal?
I’d like to know this, as well. The picture for the upgraded model shows a USB cord, but both models list a USB adapter among the contents.
Someone asked the same question on Amazon and got this reply from the seller:
the difference between Version 2 and Version3 of the garage door , V2:220V dc power supply, V3: USB power supply. Other parts of V3 version is slightly upgraded
Not the clearest answer, but it seems strange that it would cost $10 (on here; there’s currently a $20 difference on Amazon, $49.99 vs. $69.99) simply for the USB cable, right? I can’t tell whether the cheaper one has a regular three-prong plug or if it needs to be hard-wired. If it’s the latter, I could see why this model would be worth the extra cost.
How do I tell the company I need a special module for compatibility as it says in their image?
I have the same question about the special module.
