I love this drill. It's easy to use, does not vibrate hard and does not get hot with prolonged use. It changes quickly and does not require charging often. I charge fully about once a week with daily use. It's a great investment regardless if you are a new tech or a vet.I was apprehensive to spend so much money on this efile while there are cheaper options. However, this is a great choice. The machine is powerful, which good torque.I would purchase again.Very simple to use. The toggle switch is very delicate so be carefulReally loving this nail drill! It’s perfect for my needs doing my nails at home! Clear instructions included. I’ve only used it a little bit so far… so I’m hoping it will hold up well over time and to more use. I’ll update once I’ve had more experience with it. Definitely no joke the speed and power of this machine when turned up to high speed especially!! Might recommend a mask while using so you don’t breath in acrylic shavings, and be careful to have your hair or any other nearby loose, dangling items secure to prevent a risk of anything getting caught on the rotating head! I accidentally swiped the edge of the cord with one of the sandpaper heads while it was going pretty fast, and it tore the sandpaper piece loose! Made me do a double thought about what it might have done had that cord been a section of my hair instead!! Yikes! Lol So just be careful! The handheld pen portion does start to get a bit warm after awhile of running the machine I noticed, but I don’t believe that’s abnormal. I really like all the variety of bits it comes with as well and how simple they are to swap in and out of the drill! Great product!!I do my own acrylic nails. Think the product is easy to use. It seems durable which was my main concern.The product itself has been amazing, I’ve been using for a year and then it suddenly stopped working and made an A2 error, so I looked at the reviews with this same error and contacted customer service warranty department, they shipped me a new hand piece and it worked fine, for a few months, but A2 error again, Kelly at customer service is shipping another one and should arrive within a few days! I’m very happy with this efile and the customer service has been so great that I’m happy to keep my efile and wait on another hand piece.Like itTbh its a safe drill for beginners specially since u can adjust the speed and also they come with safety bits which are so much better than the regular ones for anyone. Overall would give this a five star and def should be your purchase if you are a nail tech.
