Honestly I don’t know what people were expecting for $40. Mine arrived super fast. Was super easy to use. I had none of the issues some of the reviews on here are describing - but I am a qualified nail tech though I no longer work as one. I wanted a no fuss little drill that was easy to use and I got one. I don’t use it at the highest setting - if you are soaking your nails properly it’s not necessary. I would have happily paid a bit extra for some better quality drill bits. But these have worked fine. I’ll probably get some better quality ones to get a quicker result down the track - but the ones provided do a good job of you know what you are doing. It just takes a bit longer. I’m super happy with it. My $40 has kept my nails looking fab through covid and saved me heaps too.
