Review on Microsoft Surface Pen Ice Blue by Rahman Lassiter

Worked beautifully on my surface pro while it was working. I used it in class today while taking notes and the black cap around the gray tip has come loose. It appears to have been used to stabilize the tip for writing. Now the tip just dangles and is almost useless. It still writes but isn't steady anymore and shakes all over the place which makes it seem like I'm writing with Parkinson's. I just bought this July 20th and its October 1st. I don't know if there are replacement tips or if it's possible to swap them out for a new one as mine may have been defective. I really hope it's defective because I really love this pen.
