## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent customer support in UK. Brilliant Product.
  

*by R***H on Reviewed in the United Kingdom on 27 March 2020*

The first one I received was defective, which is most unusual for something from Roco. It was probably a fault with the router which is made by a third party. The importers, Gaugemaster, were more than helpful, and the supplier sent a replacement that came when the defective one was collected.It is a great system for running a DCC model railway and fairly intuitive once you get used to it. You can take loco photos with your Android phone or tablet and place them with each loco entry. Marvellous bit of kit. You get what you pay for...Update. Have used for 2 months now. Totally outstanding. Purchased a Roco wireless Multimaus too as it is always ready to go. Z21 reads cv values, writes them and lets you configure your loco sound interface so you have the functions you want easily to hand. You really can't make a more user friendly DCC controller.
