1Pcs Delay Relay Switch DC 5V 12V 24V Digital LED Cycle Timer Relay Module Turn On/Off Delay Timer Switch Timing Controller with Case Protection

The WSDMAVIS Delay Relay Switch has garnered mixed reviews from customers, who appreciate its functionality but express dissatisfaction with the lack of clear instructions and some operational quirks. For those looking for a straightforward solution to implement a delay timer, this product delivers, allowing users to set a time delay after activation before the load is energized. It effectively handles delay functionality up to 999 minutes, which is a great feature for many applications. However, users have reported that the absence of comprehensive instructions directly on the product page makes the installation and configuration daunting. While some find it manageable with the help of external resources—like instructional videos on platforms such as YouTube—others encounter frustration due to a complicated setup process involving tricky button sequences. Additionally, it's noted that the relay may not behave as expected during restart phases without the trigger wire, further complicating usability. Overall, while the WSDMAVIS Delay Relay Switch serves its basic purpose of timing, it may not cater to all users' needs due to its lack of user-friendly instructions and a few operational limitations. **
