Review:
I purchased this marker about 3-4 Years ago now and I never regretted it. It never breaks and always preferms great. it is very silent which I love and feels great holding it. very smooth and easy to clean and looks great.. with teh Xchamber it is also very gas efficent.
Conclusion:
Great for begginers or pros. i used it and learned how markers work and after taking it apart so often i can strip and clean prety much anything. preforms just about as good as My new custom pro and has never let me down in 3 years.
