Good, with one thing to plan for
Pressure sensor addresses the leading cause of brushing-related gum recession. The one thing to know before ordering: Roughly Rs2,000 a year in replacement brush heads. To be fair that is written on the product page. I skimmed past it and had to rearrange things afterwards.

My mistake, but read the avoid note
Genuinely my own fault. Posting so somebody else does not repeat it. The listing says who should avoid this: Anyone unwilling to spend roughly Rs2,000 a year on replacement heads. That was my situation and I ordered anyway. It does what it says on the page — it just was not the thing I needed.

Fine, once I adjusted my expectations
Leading with the problem, because it is what I would have wanted to read: Roughly Rs2,000 a year in replacement brush heads. Seven modes, of which most people use one. Neither is hidden — both are listed on the page — but they matter more in daily use than they look on a spec sheet. I have kept it, for one reason: Pressure sensor addresses the leading cause of brushing-related gum recession. That still outweighs the rest, but only just.

After a few months
Had this six weeks now, so this is not an unboxing opinion. Oscillating-rotating action has strong clinical evidence for plaque removal. Still mildly irritated by one thing: Roughly Rs2,000 a year in replacement brush heads. Known trade-off rather than a fault, though, and I would buy it again.

Specs match the listing
I compared four of these on paper before ordering, so the line I actually checked was "Battery". The page says Lithium ion, about 2 weeks per charge, and that is what turned up. Pressure sensor addresses the leading cause of brushing-related gum recession.
