Review on ⏳ Countdown Control Function for Enhanced Compatibility and Support by Jorge Maertz

I bought this product thinking it would work around my whole house and each one is great as are all 15. One barcode Scan on the back says if you can't figure it out, put in the numbers or it won't work, it's a waste of money. Worst thing I've ever bought in my life and I thought it was amazing but they really suck they would be great if they worked but you just can't get them to work
