Review (5/5): Great, improved product
I've been using beard trimmers for almost 30 years. This is the best so far. Light, powerful and very smooth. I had the prior version which was good, but not as good. I was surprised how much better this version is. The vacuum is much better, the alternate head for detailed trimming is easy to change back and forth, and the ability to use it plugged in is a big plus. The prior version could only be used in battery mode, and when the batteries wouldn't recharge after a couple years there was nothing to do but tear it open, recycle the batteries and throw the rest away (the batteries were soldered, so I couldn't just replace them). Norelco does recommend running the battery until the charge light comes on, and then recharging it (probably NiCad batteries), but this is no problem if you can use while charging. It also charges quickly and indicates when the charging is finished.
I shopped around, and Amazon's price (when I bought it) was the best around, online or in stores.
