Q: I'm trying to get my eyebrows to fill in after years of over tweezing. This product is easy to use, using the brush applicator in the lid. Just once a day at bedtime, I paint it on my eyebrows. I have very sensitive skin, and this serum doesn't irritate my skin. I'm looking forward to this product giving me my eyebrows back.

A: positive
****
Q: We bought two of these.This product. Does not fit 128 disk. The folders are so tight against the edge once you start filling it. It becomes impossible to out disk in towards the back of the case. Will be looking for somwthing decent.

A: negative

Q: Very comfortable. Can use for hours on end with no discomfort. Haven't had to charge it since I bought it months ago, albeit I don't use it every single day. Love the functionality, the accuracy, and the feel of the materials and size (I have big hands). Only thing I would say to look out for is this: I do a lot of editing of music. This requires a ton of zooming in and out using the main scroll wheel. Because of the mouse's infinite scroll function, I sometimes accidentally activate it and it might zoom all the way in or out in an instant and I lose precision in this way. However, I did get used to that, and learned where the threshold is for the function, and how to manage the scrolling.

A:
positive
