WAHL Stainless Steel Lithium Ion Rechargeable Hair Clipper/ Trimmer, Model 9818

works great, best trimmer I've ever owned, one product that's a little pricey but definitely worth it.

My husband doesn't have a ton of facial hair so he doesn't really need razors, but he hates using foil shavers because they pull and snag his facial. Ouch! He loves this Wahl trimmer and is so impressed at how precise and sharp it is. I just gave it to him for Christmas, and so far so good.

This trimmer is the best I have had so far. The power last for weeks when just trimming my beard. I have not charged it yet since the first time.

I was looking for a cordless trimmer that would do a better job at getting a well defined line on the edges of my beard than my Norelco vacuum trimmer/cutter. Note that this is a trimmer, not a cutter meaning it is designed to trim, not cut a whole head of hair. While this trimmer can't be set to a "zero gap" meaning both blades are the same length at the edge and can therefore cut close to the skin (and can also cut the skin), it does cut a pretty fine line and serves my purpose. And finally the battery is lithium ion meaning no memory effect, fast charging and full power until it runs down. This is one of the few trimmers with a charge indicator light which for me is a big deal - otherwise you just plug it in and guess when it's charged. The light also warns you when the battery needs charged.

For the first 6 months, the power switch was kind of iffy - had to hit it several times to come on. Then it came on and would not turn off Had to take it apart and cut the battery cable Manually pushing the little white switch would not turn it off TIME TO SWITCH TO ANOTHER BRAND - THIS WAS AN EXPENSIVE FAILED EXPERIMENT
