Small, Efficient and Effective
Truthfully, I did not know what to expect given the mixed reviews.  Prior to using the product I checked the device Watts prior to use.  Volts * Amps...or if the device had Watts displayed I made sure I did not exceed the product Watt max.  I have used this for my Toothbrush, my Dremel, and have charged batteries for my drill and skill saw.  In the kitchen, my wife and I used it on two small blenders.  I should have purchased at least two because my wife wants to use it for her small kitchen devices.  I highly recommend this product if it is used as directed.
