TWSBI Diamond 580AL Fountain Pen - Silver, Fine is rated 4.6429 out of 5 by 14.
Rated 5 out of 5 by from This is one classy looking pen. I love my TWSBI 580, and the 580AL is even better. The aluminum mechanism feels much sturdier than the regular plastic mechanism when filling the pen. It also adds just a touch more weight to the pen making it feel even better in the hand. I find the aluminum grip easier to hold than the the original plastic, it's less slippery. The 580 is a well balanced pen for writing, but this may be even better! I've seen a lot of questions about whether or not the posting "problem" has been fixed. No, the 580AL isn't made to post, it CAN post, but it's much more comfortable writing without the heavy cap on the back (and it feels like a sword if you put the cap on the back). Truly one of my favorite pens.

Rated 5 out of 5 by from Wonderful First let me say the customer service at Gouley is second to none. I ordered this on Friday and put a little note with my order that I had a huge presentation this week and would like the pen for that. Well they shipped it that day and now I have it in my hand on Monday. Just amazing. The pen itself is a beauty, just wonderful to look at. It writes very well, no skipping, inked it up and started writing away. Even on cheap Staples legal pads it writes wonderfully. This is my first fine nib, as I have only gotten into the fountain pen scene about a month ago, and I love it. It gives a little more feedback than my medium points but it very smooth. I am very happy with my purchase and Goulet, which will be my go to retailer going forward.

Rated 4 out of 5 by from First fountain pen - not perfect but pretty good Pretty happy with the pen, it writes quite well. Not as smooth as others I tried in the shops, but pretty good. Looks great, and feel great in the hand, although I don't recommend for people with XL size hands like me - since you cannot post, it makes the pen just fit OK. The main issue was the clip - it was loose, and TSWBI said its designed that way (it to wobble from side to side when looking at it straight on!). I had to make my own fix for this (which wasn't hard admittedly, but shouldn't have had to be necessary). Giving it 4 stars.

Rated 4 out of 5 by from My personal favorite for my projects I bought this pen together with Noodler's Konrad, and that was one of the best decisions I chose in my life. The 580AL Fine nib writes so smooth supported by constant flow of ink and the solid material that build the body of this pen, taking notes on my work has never been so effortlessly. The diameter of the pen itself really helps reducing fatigue for my big hands. And what I like the most about this pen is that this pen really shine the most where my Noodler's Konrad won't, so they complements each other so well. Did i mention about the body material? it's feels so solid and warm in your hand!

Rated 5 out of 5 by from Outstanding Value This is an excellent fountain pen. If I were given the pen and told to guess the price, my estimate would be well over one hundred dollars. I can't think of another pen for less than one hundred that comes anywhere close to this pen. In fact, I think you have to go to a Lamy 2000 to beat it. The nib is smooth but with some feedback. I like a smooth nib and I keep the micromesh handy, but I have not found it necessary to change this nib in any way. It holds a lot of ink. The aluminum parts add a few grams to the weight making it perfect in my hand unposted. When posted it is too long and unbalanced. The threads are precisely cut and the pen fits together like a fine watch. My only complaint is the metal grip section. It is a bit too slick for me. I prefer the plastic of the other TWSBI pens.

Rated 3 out of 5 by from Not worth the price. The pen looks great, but when I held it in my hand I was disappointed. It felt cheap for my tastes. The aluminum didn't really add much weight to it, as they're very light pieces, the cap having all it's weight concentrated in the cap makes it heavier than the pen itself. You CAN post the cap, and a lot of people say it feels awkward, but it didn't feel that way at all to me, I actually prefer writing with the cap posted. The nib has a weird feel to it when writing, it's not smooth as most people say, it was the feel of very subtle feedback. The twist mechanism didn't turn so easy, it took me about a minute to finally get it working. I had to use to much force to turn the knob, that it loosened the mechanism and now it's kind of flimsy. I'm definitely not buying another one, I'm sticking to German and Japanese brands.
