Not sure what one of the side buttons does yet, but this is definitely much better quality for $40 less.

I use it on a Lenovo Yoga 720 13" and it works like a dream, very responsive on Adobe apps (PS, AE, PR) and Microsoft apps like Fresh Paint and One Note.- Very good build quality does not feel cheap, has a solid aluminum feel to it, stronger than a pen/pencil feeling

I think the thing is a hunk of junk but necessary and is simply a poor design quality in my opinion, which we all know is not worth a plug nickle in the grand scheme of things.

I like it because is easy to use and has perfect quality

Excellent quality

This pen is just poor quality and has a short lifespan, which is very disappointing because I do not want to spend $30 on this pen every 9 months.

It is a nice feel pen and seems good quality

Very good quality and nice feeling when you writing

Did not use but seems good quality

Quality seems good and easy to change batteries.

The battery it came with was not in the pen, but it was corroded so I went and purchased another AAAA battery (that's not an accidental additional A).

I would be MORE than happy to give you 5 stars if yall could fix my issue
