For its price, it's okay. I received it in a week for personal use. I recommend it because it has a good speed for using it on yourself, but for business, I don't recommend it because it's not strong enough for professional use. I don't think it will last long if you use it professionally. Otherwise, everything is fine. I'm happy with the product.
Very fast delivery, package is well. All inside are new. Easy to work, polish pen is ergonomic. It’s easy to charge. I’ve already tried it, it’s working well.
