    Great value for the price. Works fine, with good range. Accept almost every plug kinds and more than one at time. Very usefull with devices that have not on/off button. Has adjustable pins...
    Correct package and presentation for the price...
    Good choice for the price. Very usefull.
  • Very good Wireless Remote control

    I bought 10 sets of this model of remoteI am very happy with them. They consium low power, long-range .Working frequency: 433.92MHz, Control modes: Latch (L), Unlatch (M), They report excellent price! Honestly recommend!
    Although the figure is frameless reception I received as a bonus the 10 sets with case!The wireless receiving controller, with high-security, stable performance, low power consumption.
    radio remote control high quality, robust and stable!

    As I expected when I purchased it, the control works fine at 115VAC as well as 220VAC. The reason is that the low voltage for the receiver is obtained by dropping line voltage and then rectifying and filtering it. Voltage is dropped through a 0.56MFD 300V capacitor using it's reactive impedance. At 50 or 60 Hz power line frequency the capacitor "looks" like a few thousand ohms, BUT unlike an ordinary resistor it doesn't generate any heat. This is a time honored way of dropping line voltage for low voltage devices.This manufacturer doesn't offer the control in a 115VAC version, but if he did the only change would be to substitute a (typically) 1.0MFD 200V or 250V capacitor. But that's not absolutely necessary, and the unit works fine at voltage as low as about 80VAC.There's a switch in the upper left corner (actuated by a toothpick or ball point pen) and an LED in the upper right corner that I "think" indicates when the unit is in learn mode. Instructions on the box indicate that the unit can learn up to 50 different codes from remotes. It's too bad this isn't described better, and provision made for where to get additional remotes. The process of setting the transmitter's code requires internal soldering, and is not something the average user would be able to do.There are other DealExtreme controls that perform this function for a few dollars less, some sold in 115VAC and 240VAC versions. Unless you need the learning feature (and are technically skilled enough to figure out how to use it) this control is not the best value.And don't be fooled by what appears to be a third grounding pin in the receptacle. The metal contact in that hole is not electrically connected to anything. This is strictly a two-blade receptacle as far as function goes, although it does accept blades that are vertical (parallel), horizontal, or skewed as on Australian plugs.
    A nice, compact control with good transmitter range and able to operate at 115VAC or 220VAC.
  • Very good item

    The device works in large distance. It is easy to instal into the breadboard. Stable signal is issued. Wide application, because there are four outputs with 3.5 V voltage. The standard operating frequency can be easily tied to the control module, standard RC remote control, thus allowing the device utilization.
    The device can be used to drive 5V relay. It can also be used as a simple one-way switch.
    The device according to their potential is worth the price.
