I received this wonderful piece of technology for Christmas. I have used it everyday - literally - since. I have since gotten nearly every accessory. (Headphones, several notebooks, the portfolio, etc) It works wonderful with my DellWin10 laptop. In order for the pen to work to its fullest potential, you must download the Echo Desktop software from Livescribe.I have had no problems in these three months of HEAVY use. (As I said, daily since Christmas, and even then - hours at a time.) The audio recording quality is superb and with sound editing software I have, makes recording sessions a breeze. The echo desktop can also export written livescribe pages to both pdfs and word docs. Both are a fantastic way to record your writings. The battery is a very long lasting, (again, daily,heavy use) going several days on one charge.If you have this pen, be sure to explore all the options and settings, there is even a piano - yes - piano template that will actually play music that you write (my sister was sold on this option and has since gotten one for herself). There is a translator option for several languages, (you write the word in your language and it translates it into the selected language on the pen. (Livescribe -- if you read this, please add a Russian option as I am actively learning the language, there's no option on the Echo app store.)There are several notebooks you can use at once. Each sequence has a 1-8 number. It is important that you have only one number of each style at a time, else the pen will write over itself. Once your archive a notebook, you can use that sequence number again. Please note, this only is for each size, so if you have an A5 #1, you can use an 8.5 x 11 # and a printable notepad (yes this is a thing) #1 at the same time.I highly recommend this pen to anyone who is in school, an author, or any type of creative. This pen is expensive, yes, but so, so worth every penny.
