I ordered a 3-pack of stylus for my HP Jornada 720 handheld computer from eXpansys (also known as MobilePlanet.com) to use as spares in case I lost my original. When they arrived the problem was immediately apparent.  
 
The styli I received were over an inch shorter than my original stylus , and too small in diameter to fit in the stylus bay of my Jornada without falling out. My original stylus has a pocket clip that served to lock the stylus to the computer, but the Mobile Planet styli had simple nubs instead of a clip and were completely non-functional either as a pocket clip or to lock the stylus in the stylus bay on the computer. In fact, comparing the styli I received to the pictures on Mobile Planet’s webpage, they were completely different. And yet the sticker on the simple plastic bag the styli were packaged in read “eXpansys Jornada 720 Stylus Pack’.  
 
So I got an RMA# from eXpansys and returned the styli for a refund. Since the problem was all theirs either in mislabeling or misrepresenting their product, I requested a refund of my return shipping as well. After waiting 30 days for them to “inspect” my return I received a refund for the original order amount, but not my return shipping. Looks like I’ll have to contact my credit card company and see if I can start a dispute. Luckily I did screen captures of eXpansys’s webpage showing the styli I ordered, and took some digital pictures of what I received, hopefully these will expedite getting a refund
