Philips Philishave HQ8894 Sensotec Mains and Rechargeable Shaver

I was a big fan of Philishave until I changed my old Philishave (model 975). I bought my new Philishave HQ8894 a year ago and I am not satisfied with the product. The reason is that after four months it started to create a problem of charging and I took it to the shop that I bought. After two months waiting they gave me brand-new HQ8894. This is because the water somehow leaked inside the unit and damaged the integrated charging system which it should not. After I have received the new one I found out that something is wrong with its pop-up trimmer (it was noisy and basically did not do a good job for grooming sideburns. I prefer the old Philishave over-all.
