I purchased a philips qt4001/15 from. Flipkart website. I am very satisfied with this product .
Only Because of No led Light Indication While it is in Use thats why Giving 4 Star.
Pros:
1) Battery backup is good comparable to old models of Philips Trimmers.
2) Adjustable trimmer head.
3) Blades of the trimmer are round in shape so no cuts & Blood.
4) Slim design & easy to hold
5) No need of oiling.
6) 3 Years Warranty( 2yrs 1 Yr on Philips Website Registration)
Cons:
1) No LED light indication when Trimmer is in Use.
2) Vibration & Sound of motor is irritating.
3) Takes Excess Time To Charge it full.( i.e.10 Hours) .
Regards.
