Well. Let me share my experience with this specific remote control. I bought it on Saturday 10-10-2020 in the afternoon, and as expected, it was shipped on Monday 12-10-2020. Today, Tuesday 13-10-2020, I received it from speedeX in Pylaia-Thermi at 10:30 am (since I don't have a residential address - off the grid) and as soon as I got home, I tried it. The build quality is average, but for its price, it's great. I didn't need to do anything for it to work (it was already synchronized, of course, for a nova receiver). Its response is very good (much better than the factory remote control of nova that you had to press as if there's no tomorrow for it to work), with a gentle touch, each button responds immediately, and any delay is from the receiver, as when you press a button softly, the receiver's indicator light immediately turns on, and at least my receiver takes 1-2 seconds to respond. I highly recommend it.
