    1. Great new design features
      Improvement over the original. The lockout feature is an great option. Hoping it comes to the original Open 2 in the future. The new ink cartridge it writes a lot better.

    2. Better than the original
      This pen is a great improvement over the original. The lockout feature is an added plus; hoping it comes to the original Open 2 in the future. With the new ink cartridge it write a lot better than the original. It is heavy for a pen, but if you like that copper look it is well worth it.

    3. Great quality pen/light with no ink issues
      I read about the ink issues with the first release and was a bit apprehensive to buy this release. I have to say that the new gel ink cartridges work fantastic and they dry a lot quicker than the pilot G2 I am used to. No more smudges!
      This thing is heavy! So be ready for that. If you do a ton of hand writing it may put a strain on your hand, but if you have big hands the larger size feels better. The light works great and has 3 brightness levels. More than you would ever need for light duty needs. Its great for the office so I dont have to EDC a separate light.
      Be aware the copper does patina. I have a S2R Baton II with the same finish and its meant to do this. If you want a pristine copper look 100% of the time you are not going to get it here.

    4. It’s better than the OG
      This pen is machined better, and the cartridges are better than the first batch. I’ve only had it for a few days now. But I will say I like it more. However I was noticing today that it is starting to oxidize/patina already so I’m not going to recommend this if you are a technician/mechanic. I’m currently in the process of trying to find something to get the smudge marks off of it.

    6. Vastly improved
      I liked the original version of the O'Pen and did not experience the cartridge problem as did some others. This CU version and the new cartridge is simply amazing. Yes, it is heavy, but it has a good feel and writes beautifully. If you are hesitant to purchase due to the comments on the original, don't be. This is a great pen and it will only get better in it's appearance because of the copper.
