AO Smith EWS-3 3-Litre 3000 Watts Instant Water Heater (White)

I think it is the worst choice one can make for instant water heater. The service is so worst that I had to call my plumber to install the heater properly. Let me explain my experience chronologically. The product came in proper packaging within the time assured by Amazon on 8th May. Then I received a call from AO Smith for installation. The guy who called me was very helpful over phone and he promised that he will come around 11am on 9th May. He has asked me to install the angular taps prior to his visit. But on next day he didn't turn up at 11am so I called him up. He said he may not come on today as he has a product demonstration to attend in his office. When I said I need it to be installed today only then he said he'll come around 3pm. Again he didn't turn up at 3pm so I called him again and this time he said he is not sure whether he can come or not. Then I asked him to handover the phone to his superior and that person ensured that he'll come by 4:30. Again he failed to come within that time and finally he turned around 5:30pm and after reaching he asked me to buy a 16AMp 3pin socket. When I went out to buy the socket he again called me up and said he need to connecting pipes each measuring 18 inches which he can provide but for that I need to an extra amount of Rs.450/- but I bought those pipes (good quality) from a local hardware store at a total price of Rs.200/-!!!! Then after fixing the pipes and 3pin socket he said the heater is not working and he opened up the outer casing of the heater and while doing that he broke one of the two indicator bulb holders. As you can see in the picture that one indicator is not working. He put the blame on Amazon for mishandling the package and some what managed to install the heater and almost flew off taking the service charge of Rs.250/-. As he left I turned on the heater to check whether the heater is working properly or not and as I turned on the heater one of the connecting through which hot water comes to tap came out of the joined as it was not properly fixed by him. I called him up immediately but he refused to come again and asked me to get it fixed by my plumber and for that I had to call my plumber and got it fixed. So, I am very very dissatisfied with the product and service of AO Smith. Won't recommend anybody to buy this heater and considering the standard of installation service I'll ask not to buy any product of AO Smith.
