Review on 🔌 Wireless RF Relay Remote Control Switch, QIACHIP 12V 1CH 433Mhz Momentary Light Transmitter with Receiver (1 Relay) by Mario Beckwith

I have the 3-receivers 2-keyfobs with A/B/C buttons combo, for front/mid/rear aux offroad lights in my van. I really like the idea of wireless control, so i don't have to mess around with running/hiding long wires for the pushbuttons on the dashboard.First keyfob programmed without issue. Second keyfob was not able to connect to the receiver, tried it multiple times. When a key is pressed, the keyfob LED was half as bright as the other key's. I thought the battery may be low, and opened it to check the battery voltage. It is a 3V CR2032, and measured 3.1V, which is good. Upon reinstalling the same battery (effectively a reset), and pushing the keys, the LED now appears equally bright as the other key's.I was then able to programmed it without issues.Another con is the plastic housing, the top cover has 2 mounting holes for screws in addition to snapping into the bottom. Once mounted with screws, you can't access the programming button or wire terminals. For access, you must remove the screws, then unsnap the top cover. You can avoid this by using double-sided tapes on the bottom cover instead of screws.Overall the setup works as expected, I have good range around the vehicle with either keyfob without needing to uncoil the antenna as some suggest.minus 1-star for the hassle.
