Got my dot installation done today it exactly took 30mins for the whole process and in my case as the 15A plug was quite near so dint have the need to connect it to the meter.
I was happy as there were no ugly black pipes running between the meter and the charger.
The guys were experienced and exactly knew what they were doing.
But I have one complaint with ather on dot installation in my case there was no extra wiring and other stuff and felt compact hence I felt 1800rs is very much for installation. And during payment also they told me the subscription plan I was given complimentary for 1 year was ather service and not ather one. I think for previous customers u had been giving ather one and not ather service.
