## Customer Reviews

### ⭐⭐⭐ 







  
  
    Poor description, be cautious
  

*by A***R on Reviewed in the United Kingdom on 20 February 2018*

Description of product does not say that it can only switch 75V AC or more. I needed to switch 12V DC and so these were no use.I do not know if the product is a good one or not, I have rated the product low due to the lack of info in the description, this info is not even in `product details` but lower in the extended information.

### ⭐⭐⭐⭐⭐ 







  
  
    Works fantastically, but make sure you get a schematic
  

*by P***E on Reviewed in the United Kingdom on 28 May 2013*

You look at a board and assume it works one way... and then you get a loud snap and a cloud of magic smoke. Always read the schematic. Other than that, works brilliantly (I bought a second one after realising my mistake). Well put together bit of kit and at a great price.

### ⭐⭐⭐⭐⭐ 







  
  
    Great for AC power
  

*by J***E on Reviewed in the United Kingdom on 3 November 2017*

Great but remember that these are only good for AC power (e.g. mains) and no good for 12V DC for example
