RotringMulti-Function Pen, Four-In-One, 0.5mm Mechanical Pencil with Black/Red/Blue Ballpoint Pen in Triangle Package (502-700F)

I had one of these twenty years ago (and lost it) and replaced the ink with Schmidt cartridges because the original were so difficult to write with. This one however, writes very well. Though it is a larger pen (not quite double), it is easy enough to manoeuvre.This writes smoothly and cleanly. I like the weight and find this build quality very good. As for value for the money- it depends. obviously a Uni Jestream trio is cheaper, but this is not plastic and should last longer. Just keep your eye on it- someone might try to pinch it.

I have been using this writing tool for the past several months. its quality is obvious and all of its component pieces fit together perfectly. It has a nice weight to it but I don't think its too heavy. Also I was a little worried about its diameter and how well it would fit into my hand. Its really not much bigger than my other mechanical pencils and does not at all feel awkward. The selection method works great and I can always select which pen or pencil I want. I actually took the thing apart to understand how it works. Retract the nib by pulling up on the clip. It is spring loaded and makes a nice click when it retracts or extends. To select a pen or pencil retract the nib and then place the tool in a horizontal position and rotate it until the picture of the pen/pencil you want is facing up. Then just push the plunger and out comes the selected nib. This tool is so well built I expect it to last for my lifetime. I am happy with my purchase and I would buy it again.

It is a excellent product, useful.

I love this pen. I have carried it with me all the way through engineering school. Its built tough and easy to use. Having 3 color options and a pencil makes doing design sketches and graphs really easy. Its heavy, but not so heavy that my hand cramps when doing homework. Some of the paint has chipped over the years, but it just makes it look loved. Only complaint is that the eraser is small and basicaly useless. So i just keep a good eraser with me. Great Pen!

I'm a contractor and work with plans on a daily basis. I was looking for a mechanical pencil, red pen, and blue and black ink in one instrument so I could stop carrying multiple pens/pencils all day. This fits the bill and overall I'm very happy with it but has a few drawbacks. For the positives, I love the selection system and small diameter of it. It feels like a normal sized pen but has all the functions I need.The ballpoints don't write all that smoothly, and I'd expect a little better feel for the price. I'm going to continue using this so I'll replace with better refills when I need to. I've found the mechanical pencil to be pretty unreliable. I understand the size constraints but the thin graphite breaks quite often even while not being used so I'm constantly having to clear out the broken piece and then click away until the new piece loads (This could also be the pieces breaking in the storage tube prior to loading into the tip). I'm pretty rough on this so at a desk it will probably be fine. Lastly, the finish is starting to come off. Again, I'm very rough on this and using it at a jobsite but if the finish comes off where the selection icons are located it will become a problem.Overall I'm very happy with this. The negative points above combined only lead me to take off one star. I'd pay twice as much for a little more rugged version with a sturdier pencil.

This pen does have the paint and metal start to fade in less then a week. My mechanical pencil gets stuck and all the lead constantly breaks. The mechanism catches all the time. D1 refills hold like 1/10 of a pen. Gel pens are like a paragraph. The pressing of the clip makes my thumb hurt. Look at the complaints. D1! How can it possibly hold any amount of ink. It gets stuck CONSTANTLY. The paint chipping is real. It’s heavy. Refills are $4. This is the worst purchase. Build quality. Bad. The value of refills. Bad. The finish and paint. Bad. The weight. Bad. The refills are as thick as a toothpick and 2 inches long. How?? How can this be a usable pen as far as laws of reality?? It probably weighs as much as a calculator but in the shape of a pen. All these things are in other reviews. Smoothness: It can’t write smooth. Ease of use: It gets stuck and lead breaks and it’s heavy and the retraction clip is stiff. Ease of everything is bad. Expensive. So expensive. $45 and then $4 refills for a page of A6. It’s trash. Everyone is going to think I am just mad but it’s frustrating. It can’t pass a trial of 10 people. No way its 4.4 stars. What do they like about it? What is even designed to work on it? This is waste like a styrofoam cup or a $2 phone stand. I didn’t buy things for the ocean creatures to get stuck in.
