## Customer Reviews

### ⭐⭐ Kit not as listed in tittle it's a 10mm kit
*by A***6 on 20 December 2023*

Kit is listed as a 16mm cable in the tittle but it actually comes with 10mm cable. The 10mm kits are cheaper so seams like they are misleading people by stating 16mm to try charge that bit more. Rated 2 stars as the relay looks decent and kit also has everything needed but a inconvenience having to return and reorder another kit
