I have been using the Philips 4000/15 trimmer for an year now and its so much better than my previous trimmer.
Its very easy to handle and use. There are 20 trimmer length setting ranging from 0- 10 with 0.5 mm setting difference which is really good. The 0.5 difference in each setting makes it very convenient to shape your beard in the desired style.
Another great thing about this product is that after purchasing you can register the product on Philips website and get an extended 2 year warranty free.
This trimmer is for cordless use only and takes 10 hours to charge to provide 45 minutes of cordless use.
Overall it is worth your money and I would recommend you to buy this product if you are looking for a good trimmer in reasonable price.
