are you looking for a tondeuse that is the closest thing that your barber uses because you want to cut your hair at home? have you been looking around and wanted to pick the familiar brands - Bosh, Phillips..., but they just didn't seem like those professional ones? All of the familiar brands, function with battery, probably have to finish charging before use, looked shiny, weak and plastic. Well, Wahl is probably a famous brand but I didn't have any idea, and I picked it because I thought it looked like those used in barbershops.
If you had similar search experience and attitude to what you want as I have described above, this is just the tondeuese you are looking. I just used it. Pleasantly heavy, an abundant number of combs (colors really help and its not just a fluke).
Only downside, if it is a downside, it warms up a bit - which really doesn't have an effect on cutting your. Highly recommended.
