## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good, neat and well made
*by L***Z on 20 April 2025*

Really good, standard relay but having the wires fitted means it's neat and better to prevent corrosion and loose contacts. Used to replace an old rusty relay and looked great, worked well and I'd expect to last along time

### ⭐⭐⭐⭐⭐ Works fine
*by A***M on 6 November 2023*

Works perfectly. Binned the and soldered directly to the pins so no idea on that bit.

### ⭐⭐⭐⭐ Excellent product
*by J***D on 7 December 2021*

Required this for a relay switched circuit, easy to install and works well.
