Some Reviews about it:

Delivery & installation and after 1 year
Ordered on 10th August at 8.00 p.m. & got the delivery on 11th Aug at 7.45 am ( 5 ☆☆☆☆☆ for delivery)
Made a call to Kent at 8.00 am & technician visited at 10.00 am & by 11.00 am product installed (5☆☆☆☆☆ for installation)

Current borewell water TDS- 2050
Kent output TDS- 200

What I've noticed in short time is that taste of filter water is good BUT wastage is quite high, I mean... approx 35 Ltr is wastage water for 8 Ltr tank.

Will write soon more about product if & buts.

**** now after one year *****
Found some taste issues in water & booked a service executive visit via Kent app & very next day executive visits & found TDS level has gone up to 600 & muds & some other heavy particles has gone into little tiny inlet pipes & suggested to change 3 filters , details are...
1- Inline sediment filter
2- Inline carbon filter
3- POWP-Sediment filter
( pictures included)
Total damages done Rs 1200/-
Now things back to normal & taste has improved.

TDS metre should be there while installing
Make sure while installation the service person brings TDS metre to ensure the water quality. For me he just setup and went. I was suffering from infection then raised a call and tuned the TDS controller.

Some Reviews about it :

Aquagaurd is synonym with water purification
We have been using Aquagaurd water purifiers since 1997 , its been 20 years and the water purifier installed in year 2003 is still in use at my home. So naturally when I was looking for a RO purifier my first choice was Aquagaurd. All other brands are new and I did not have much trust on them. After doing lot of research on RO and using my logical sense I selected this product as it was providing all the features of an RO at a incredible price of 9499. I will list down the features of this RO below:

1. RO
2. UV
3 MTDS with manual adjustment one can control its TDS ( I have set it on 65 - 70 TDS) , water is very sweet.
4 It completely silent , you will not realize if its running or not and water filling rate is fast enough.
5. It has auto shut
6. Looks beautiful.

I had seen some negative reviews about service and installation, I really had doubt on those reviews as in my 20 years of experience with Aquagaurd they have never disappointed in their service in a small city like Bhagalpur, I those reviews had created a doubt in my mind that Aquagaurd might have drooped thier service quality now. But it was no big surprise to me once the product was delivered the Aquagaurd guys called me very next day and got it installed. No extra cost of installation and no selling of extra product during installation. The guy came , installed , gave demo and went. It was very smooth. Received call from Aquagaurd confirming the installation.

Guys I would suggest go for it, its better tham Livpure and Kent, moreover the brand is the first company in India to provide advanced water purification solutions in India , no one can beat their rich experience. All other have just tried to copy them and have hired stars to promote their product. Remember they have to recover the cost of hiring stars. Aquagard does not need star as its a star in itself.

Good to have n prompt service (please make sure abt water pressure)
Product is good,easy to use.
Auto stop feature is good.
Installation was done in 2days. (Placed installation request on Saturday and technician arrived on Monday (Vasai(w)))
Just one issue is that at Amazon there is no mention about product may need a booster pump which cost around 2200rs,in my case it was need. As It was my first water purifier it would be good if I know prior abt the pump then could have ordered the same as along with the product.
