Make sure the person you are using for the set-up call knows what is going on. ### ⭐⭐⭐⭐⭐ Perfect! *by E***G on Reviewed in the United Kingdom on 3 February 2020* Good quality. Hard to find right setting at 1st but now I have had no issues with it. ### ⭐⭐⭐⭐ Fabulous piece of equipment *by K***L on Reviewed in the United Kingdom on 14 December 2018* Does the job better than phones twice the price.
