The QT4008/49 is a straightforward short-beard trimmer with ten settings from 1 to 10 mm. Its Philips product page specifies 1 mm adjustment and a single comb. Choose it when whole-millimetre length changes are sufficient; it is a poor specification match if your priority is controlled settings below 1 mm.
Ten settings do not mean ten separate guards
The QT4008/49 uses one adjustable comb. That reduces loose parts, but makes the condition of that one comb important: a damaged tooth or unreliable attachment affects the length-control system, even if the motor still runs. An older bundle with a handle and charger but no comb is therefore a materially different proposition.
- Supported range: 1-10 mm on the documented comb.
- Adjustment: 1 mm steps, rather than the finer intervals of some other Philips models.
- Power claim: Philips lists 90 minutes cordless use after a 10-hour charge for this particular /49 product.
Use the range to rule a purchase in or out
For someone who alternates between 3 mm and 5 mm, the published range covers both targets. Someone trying to compare 0.5, 0.8 and 1 mm cannot make that choice from the QT4008’s guarded settings. Removing a comb is not an equivalent substitute for a documented adjustable short-stubble system.
The ten-hour charge also makes this a planned-charge tool. Compare it with another trimmer using both charge time and the lengths you need, rather than treating a larger runtime number as an overall performance score.
What to ask a seller
Request the QT4008/49 label, an image of the comb fitted to the handle, and confirmation that the complete adjustment range engages. Do not transfer the 0.5 mm settings of a similarly named Series 3000 model to this one: the series label is not a shared specification.
