I like how it feels in the hand,
but the biggest downside is that if you need a size that’s not on the top of the pen, you need to insert that attachment in the bottom and then insert another 5 attachments to get the one you want on the top.
Also this is minor but the attachments were heavily lubed before shipping but since the packaging has no plastic protecting from dust, the greasy attachments accumulated a lot of dust during the shipping process.
