The remotes are very imprecise and usually don’t work until you press them a lot of times. One of them came broken. Never received an answer from the seller. Even of they work when they are close to the receiver, once you install them on the wall they stop connecting to the receiver.
Orderd, paid and item delivered in 8 days, during the pandemic, great service. love the product and will be using it soon for a special project I have a recommendation; Please remove the switch cover prior to sending as it is really difficult (without breaking that tabs) to remove the switch cover and insert the battery.
