I am on my second SweetLF shaver. The first one failed after 2 years, so I bought this, what I thought to be an upgrade. The battery life is good, (very good) and the heads work well for a close shave. I do question the size of the shaver body, it's not the most ergonomic I have used. But, after 7 months (light) use, the unit would not turn on. I have contacted C/S, but they seem to think the heads need cleaning. I have always kept the shaver clean, (who would want to use a dirty clogged shaver?). After a few e-mails, the company have decided the motor is at fault, so, true to their word, they are sending me a replacement shaver free of charge. I will update my rating when the new shaver arrives.
