## Is the Philips Sonicare 4100 worth buying?

Yes. The Philips Sonicare 4100 costs £49.99, has a pressure sensor, two intensity settings and a 2-week battery, and 57,722 buyers rate it 4.2.

It suits anyone who wants a proven sonic brush with a gentler setting for sensitive gums.

## What do the two intensity settings change?

You can run the brush at full power or turn it down. As a result, it works for tender gums on bad days without changing brush.

In addition, SmarTimer and QuadPacer keep you brushing for 2 minutes, 30 seconds per quarter.

## What is in the box?

You get the handle, 1 Optimal Plaque Control C2 brush head and a USB charger, without a wall adaptor. A light on the handle warns you when the battery runs low.

## Where does the Philips Sonicare 4100 fall short?

There is no travel case. Also, the listing notes that some units are international products sold from abroad, which may differ from local ones, so check the seller before you buy.

## How does it compare with the Sonicare 3100 and the Oral-B Pro 1?

The Sonicare 3100 is 35p cheaper today and includes a travel case. Meanwhile, the Oral-B Pro 1 costs £29.99 and also has a pressure sensor, with a rotating head instead of a sonic one.
