This device does not hold a charge and must be used while plugged in.
This device needs to be plugged in while using. This means that you have to be very near an outlet while you are using it, and when unplugged, does not hold any charge. Very inconvenient, not user friendly and outdated in terms of ease of use. Items like this were sold in the 20th century. I returned the first one I bought as I thought it was defective, but when I received the replacement, it had the same issue and I realized that this is how it works (or doesn't). I am sending back the replacement as well and do not recommend buying this device unless you don't mind plugging it in every time you use it, and then sitting right by the outlet.
