I have had it since September 2020 and recently it presented a serious problem, it makes a strange noise and does not cut well, it struggles, and pulls the hair instead of cutting it. I thought I bought something decent but no,,, Maybe, you should probably spend over 100 euros for a professional one and not have any problems. Wasted money :(

I am writing about the ER-GC51, which is essentially the same machine. I am very satisfied with my purchase, it is worth every penny and more. I use it for my hair (mainly the sides/back and the top with scissors), my face, and occasionally my body since it cuts very close to 0.5mm. I like that it has several settings and I can do fades. It's a big plus that it works with both cord and cordless. And it is very lightweight.

Okay, it does get a little clogged easily but it doesn't bother me at all, a little shaking/blowing is fine. It requires a little attention when you're trimming down millimeters to avoid staying at the previous length and cutting off more.

I bought it in early 2018, I have done several haircuts with it and it continues to work fine
