I had older Wahl product which used for 10yrs. After all decided to get a new one. Seemed like good price. But after trying giving haircut to 2 of my kids, I understood that it is piece of ... well... to put politely.. it cuts hair worse than my other 10 yr old Wahl piece. So I returned it. Seems like this model having problems. Later read review on Amazon.. So, do not buy it.
It seems like this doesn't work much more effectively than any traditional Vidal Sassoon, etc., clipper set I've owned in the past, but you get what you pay for and it does an alright job. My husband has to go over his head several times to ensure all the hairs are caught, but that is pretty typical for do-it-yourself grade equipment, I think. Overall, about what I was expecting, nothing more, nothing less.
