Review on Wireless 433MHz RF Module Receiver With 4 Channel Output – QIACHIP RX480E (20 Pcs) by Ray Reeltalk
Great Buy !: my feedback
Especially for the price, these are great ! I got them to work about 400 feet with clear line of sight and they easily work from 1 corner of my house to the opposite corner of the other floor.
That means it works through a floor and multiple walls. Though they are not high security, their security is enough that I have never had any issue with outside interference.
- Works as intended. Ra ge is decent. You dlneed to use the antennas for anything greater than 5 feet.
- Defecrive!!!
