Smart curtains switch

[BlackAlys]

Does anyone have this? I've been offered a couple of sets quite cheaply but hadn't heard of this before.

Can be used on roller blinds too!

I've seen this but haven't bought one. Was waiting for more reviews.

Would love to hear from
People who have them.

Not used yet but I have researched for when renovations are completed in my home. Lots of YouTube videos about them. Generally quite expensive for what they do but using them in part of my home that's mainly used by my disabled daughter.

What brand are the ones you've been offered?
If genuinely cheap, then why not try them out. Worst case scenario you can sell them on?
