Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Customers find the relay module works well, with one mentioning it functions perfectly in the same circuit. The reliability and value for money receive mixed feedback - while some find them good and appreciate their cheap price, others report issues with them failing over time.
Customers find that the relays work well, with one mentioning they work perfectly in the same circuit and another noting they are easy to use.

Customers have mixed experiences with these relays, with some finding them good while others report issues, including one that stopped responding after several cycles and another where the relay turned off when power was high.

Works well, but noticed no mounting holes on board, not a big deal I can trim the leads on the bottom of the boards and you a good double stick foam tape to hold them firmly in place...… Hey saw some hope that are the complains about not being a high trigger but a low triggered relay, I just saw an option with this supplier offering on the single channel units a jumper to go from a low trigger to become a high trigger. it was one of the optional offers on this ad. the cost was @ 90 cents more. but it also had screw terminals for the inputs.
I do not use these for the original purpose I bought them for. If you are going to make small terminations for breadboarding wires and small electronic prototyping cables get the IWISS Mini Micro Open Barrel Crimping Tools Works on AWG28-20 JAM, Molex, Tyco, JST Terminals and Connectors (IWS-2820M AWG 28-20). That's what I ended up doing and they work great. Now these appear to be good quality and I will use them for larger terminations when working on automobiles or other applications where larger wire diameters are used.
These work the way there suppose to work, I had ordered 5v relays from China and got something totally different. I like how easy they are to use and setup. Doesn’t require a lot of power and can be powered by an arduino.
Of the five pieces I received, four didn't work properly (NC vs NO settings, only one worked), and the fifth one literally burned up after 3 weeks of continuous service. This module utilizes the cheapest relay known to mankind (the TONGLING JQC-3FF-S-Z), and the results are predictable. I should have read all the warnings, this product darned near cost me an electrical fire.
I have had much better luck with modules incorporating the SONGLE SRD-5VDC-SL-C, which are far superior. Look for modules with screw-set connectors for both the relay's power as well as the NC/NO/COM terminals; these do not: you have to either trust DuPont connectors or go solder leads on yourself -- ugly prospect.
I used two of these with an 8266 IoT module to create a LAN accessible cable modem and WiFI access point reset switch. They work as advertised and come wrapped in anti-stat bags. When I run out of them, I will buy more.
This review is for "DAOKI® 5 PCS 5v Relay Module for Arduino ARM PIC AVR MCU 5V Indicator Light LED 1 Channel Relay Module Works with Official Arduino Boards"
First off, these relays work great, if you use them correctly. The reason I gave them 4 stars, instead of 5, is because they are low-level triggered, and it doesn't say this anywhere in the description. If you look closely at the image of the under side of the relay, you'll notice that "low level trigger" printed on the board. This is the only indication and I missed it.
Good relays. Well marked as to how to hook it up (which is a good thing because not all relays from different sources are the same as to which contact is for normally open and which contact is for normally closed).
Product Summary: DAOKI 5 PCS 5v Relay Module for Arduino ARM PIC AVR MCU 5V Indicator Light LED 1 Channel Relay Module Works with Official Arduino Boards
The module complies with international safety standards, the control area and the load region isolation trench.
With the power supply and relay instructions, pull off, disconnect does not shine.
The control DC or AC signal, you can control 220V AC load.
There is a normally open and one normally closed contact.
Blue KF301 terminals to the control line is more convenient.
