Problems with the cord.
My complaint about this product is that the cord will not stay plugged in when using it to buff feet.  The actual buffing process is wonderful and does a fantastic job. Unfortunately if the plug keeps falling out my feet aren't getting buffed.  I have been using this product for about 5 months and would have given it 5 stars except for the cord issue.  I am thinking of buying a different version that has a different type of plug and hoping for a better connection. As a side note I have kind of figured out a way to hold my pinkie finger under the cord while using the micro pedi. It works ok but not perfectlly.
