Review (2/5): Not as good as the real thing
Bought a pair of these at the start of September and have gone through both by the beginning of December. Use the trimmer maybe three or four times a month so that's incredibly bad vale.
The first one lasted four trims and started to make the click of death sound as it pulled my facial hair. The second one just wasn't very sharp.
Save your money. I'm getting the proper Macscaped blades as one lasted me almost a year.
