Pros: Cleanest, closest clipper shave I have found so far.
Cons: Not the easiest clippers to clean.
I have been razor shaving my head for over 15 years now. I would razor shave in the warmer months, and "clipper shave" only in the colder, winter months. Over these last fifteen years, I have tried numerous brands and styles of corded and cordless clippers. Some were good, others were not.
I bought the Andis Headliner LS trimmers at the local Wal-Mart for about $20-$25. It came with a small zip-case and some basic attachments, as well as oil and cleaning brush. They appear to be basic clippers, a simple on-off switch, no real styling applied to the construction of the unit it's self. Simple, utilitarian, and plain.
I have been using this pair of Andis clippers for almost a year now. I shave my head and face atleast twice a week. For the record, I am caucasion with very fine hair on my head with very coarse facial hair. The Andis clippers shows no discrimination and cuts ALL hair clean and effectively. The blades are very fine tooth, and have proven more durable than many models I have used in the past. After almost a year they still cut strong, showing no signs of dulling.
The Andis clippers are comparable in weight to most basic clippers, having a heavy motor assembly. The motor is strong, comparable to most. I have yet to "bog" the clippers down cutting either fine or coarse hair. This is a good sign of both motor strength and blade sharpness/effectiveness. The switch is a simple two-position rocker that is of good construction. The cord is adequate for the weight of the clippers and power use. The blades are simple to remove for thorough cleaning and very easy to reinstall and align.
I cannot speak of effectiveness of any attachments, as I have never used any of them. I use these clippers strictly for shaving. The shave is close and clean, the closest I have ever achieved with a clipper. They do not aggravate my skin like many clippers have in the past. The design of the blade allows for easy nose, ear, and eyebrow trimming, as well. I have not nicked myself with them either. Most clippers that I have used in the past were quick to nick the skin around an in-grown hair, the Andis have not. Possibly because of how small and fine the teeth are on the blade.
The only thing I have to say negative about the Andis Headliner LS is that cleaning is sometimes a pain. There is a large cavity between the blade and the motor. 90% of the time I use the trimmers, they are being used blade UP (I'm usually leaned over the tub or over the sink). This cavity catches alot of hair. The hair clippings will collect in this cavity over time. I have NOT noticed any effect on operation by this. It just makes the cleaning process take longer than it should.
