Review: Easy to use. - As long as you have a multimeter this is one of the most reliable relay switches I have used. I have it sealed in a large shrink-wrap tube filled with hot glue freely mounted to the side of my bike.
Review: Reliable - As per usual another solid product from HiLetgo. I have been ordering from them since 2020 quite often. It started out because of the price and reviews mostly good. Now I always try and use this company from resistors to diodes to relays ect. I've only received 1 bad ESP32 and all it took was a soldering iron and 30 seconds and I was on my way. I ordered their relays 3 years ago and the same ones are going strong. So; I ordered these and wasn't let down upon opening.

## Features

- The module uses genuine quality relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A.
