Wahl Professional Cordless Peanut Trimmer - Lightweight & Versatile Beard & Hair Grooming Tool for Men - Perfect for Travel, Home & Professional Barbershop Use

I've been using the Wahl Peanut trimmer for almost 10 years. The first two I had were the standard ones that plugged into the wall. They worked great, loved them. But, both after about 4-5 yrs went "Pop!". Literary, that is the sound they make when they break and then you smell some burning and that's the end of the trimmer.So when my last one went Pop, I looked up on Amazon and was actually trying to find a 110-230V version so I didn't have to carry a voltage changer when going to Europe. I found this cordless version and decided to give it a try.I'm very happy with it. The freedom to not have it plugged in is great. Especially if you are shaving your head like me. The cord was always a bit of a pain (and sometimes too short).This shaver does not have the same power as the corded version, but I expected this as it runs on a single AA battery. The power is defiantly enough to cut through hair, you may just have to go a bit slower. If you have long locks of thick hair, this version probably isn't for you. For my beard/goatee and (sadly, balding) head it works great.I did find this cordless version is MUCH sharper than either of my previous standard Peanuts. With my old ones I could cut any which way without any fear of catching my skin. This cordless model has a much sharper blade/end. I've actually nicked my skin a couple times on my neck. This is good and bad. Good cause I get a closer shave, but I also have to take a bit more care to not dig-in as much.The charger they supply is stupid-big. I donated it the next day to a second hand store and use another one I have.I initially installed a Sanyo Eneloop AA battery and it lasted about a month (~an 60-90 minutes of shaving). I was very pleased with this. Though the Eneloop batteries are about the best rechargeable you can get.You get two Wahl batteries with the trimmer and I am only now using one of the supplied batteries. If they under perform I'll revise my review to note that.Overall though, the battery life is good and even if travelling for a few weeks I think I'd only take one extra battery.Conclusion:--The corded Peanut was a great trimmer. This cordless Peanut is far more convenient with no cord, but not as powerful.--I love not having a cord dangling into the sink and the power and battery life is fine by my standards.--Battery charger is too big for a compact device like this, I use another one I have.--This model gives a closer shave then the corded model I had. Just don't push too hard on your skin with it.
