More powerful than I thought
Overall I am very happy with it. I didn't think it would be as strong as I found it to be. The attachments are great except for the polishing one, I thought it should be a little softer (hence the 4 stars) but it still works well. I knew this needed to be plugged in all the time to be used and I am OK with that. For the price, you really can't beat the power of it. I have used several other kinds and this one worked really well for filing, removing ridges and polishing. The rechargeable ones are usually not very powerful and you don't want to run out of charge on your 4 finger. You should try it for yourself, but I highly recommend it. You will be pleasantly surprised.
