They just work!
Great 4 ch relays for my Esp32 / raspberry pi projects. I have several of these in use and have help up for 1 year in harsh environment s without skipping a beat. I have had no defective units out of three separate orders.

Cheap, reliable, easy to use
I use these for work for years, and they never let me down. Soldering quality at times is not perfect, and a little bit noisy, but at this price point it's absolutely great product.

Good product but be careful of the current draw
The 4 channel relays work as advertised. While the pictures indicate that the module can be driven directly from an Arduino board, make sure it can source that much current on the 5V input. A typical Arduino Mega can provide a maximum of about 1W on it's internal 5V supply, which translates to about 200mA. But when all 4 relays are turned on, the 5V draw is about 280mA. Recommend that an inexpensive (external) DC to DC supply is used to provide the 5V to the relays instead of the Arduino board as was shown. Note that the relay board even has a pin which can be used to provide that external power once the jumper is removed. Gave it 5 stars though because it works just fine. Good value for the cost.

Poor quality
Poor quality. Some relays got stuck after a short time.

Relays Are A Go.
Seems like a solid unit, but don't get carried away. I made a video demo. Just great with a Uno or other 5V unit, ESP8266 (3V MCU's) needs a transistor switch in between (the IRLED of the opto + the 2V of the indicator LED make for marginal performance otherwise). Same principal applies to other offerings (1ch, 2ch, etc.)
