## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works well
  

*by S***S on Reviewed in the United Kingdom on 3 November 2019*

Very pleased, works well but a nuisance setting it up.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Good but the sticky pad is not good
  

*by A***A on Reviewed in the United Kingdom on 23 May 2019*

In general this is really good, especially if you have cars without a rev meter like the Toyota aygo.This thing heats up a lot. And sometimes it would stay on even when the engine was turned off. For this reason I had to return it because I was worried it may kill my battery.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    OBD 2 doesn't work in my car,  SAT works well.
  

*by A***R on Reviewed in the United Kingdom on 26 May 2019*

I bought this mainly to give me a accurate speed limit in my UK 2006 Toyota Landcruiser LC5 when driving in europe(km's).Apparently my car is not obd2 compatible.  It still works well using the satellites but you loose it in tunnels.Still better than nothing.
