The pens do write pretty well, but the pocket clip is too fragile.

I bought a pack of 50 for my business a couple months ago. In that time, every single pen I've used (about 20 so far) has ended up in the rubbish with at least three-quarters of the ink still in it. The 'core functions' of the pen (ink flowing and the nib getting moved in and out) are satisfactory. But when I go to clip the pen to my pocket, they have far too much tendency to break. I can't just put a pen loose in my pocket, because it would fall out when I sit in the vehicle. It needs to be clipped to the pocket, using the clip thing on the side of the pen, so it doesn't fall out.
If I had the receipt handy, I would have taken it back and demanded a refund. Certainly not going to buy them again.

these pens dont work very well. quite patchy

We purchased a pack of 50 atleast 60% of them do not work. Don't waste your money on these pens.

Pens quite often fail to write, not a very good product

ok but can be patchy in writing
