Tab S4 Pen EJ-PT830 Stylus S Pen Replacement Tab S4 S Pen for Samsung Galaxy Tab S4 10.5" T830 SM-T830 T835 T837 Pen Tips Nibs Tweezer Micro USB to Type C Adapter and Needle Repair Part (Black)

Works as expected

After just a few weeks, this pulled apart at the middle seam and now will not stay together while being used, although you can close both portions togehter and not be able to see there is a problem. As long as you hold stylus anywhere near center seam, it starts to come apart right away. Insides are made of old stylus from Note 8 tablet, interestingly, although I cannot pull it out and at least use that part with my old tablet.Adaptor works fine and is a tight fit. Have not tried replacement heads. Found genuine Samsung stylus' on ebay for $7 each if I bought two, and have been using one of my two for past 5 - 6 weeks with no problem.Don't waste your money on this. Construction too shoddy.
