I bought this product because I like working for scientific work with the reference management software Citavi. Using the pen I find it very easy to extract any citations. The pen is pretty accurate. However, it should be ensured that working with legible copies / printing, as a "cl" also quickly can be a "d" times. The pen is super light and fits comfortably in your hand, and the USB port on your computer works well. If you loose mastered touch typing writing, it may come in the long term in a similar speed, but it remains nevertheless simple. The price is definitely worth it!
