Excelente producto!

Works great

Worked for two weeks then the tip stopped responding 80% of the time to my Surface Pro 4The eraser end still works and the cursor shows up when holding the button so I believe this is a hardware fault within the pen itself.Another thing is that for some reason pressure doesn't work with my pen, at first I thought it was a software issue but it seems to be hardware as well.I do want to mention that there is a known issue with this specific pen where the ESD (electro static discharge) protection varistor will fail and cause the front to stop working.Another thing (that is a seller fault not product fault) is that Tech EXPRESS is selling pens that are from Fulton County Schools, they are wrapped with a horrible feeling aluminum skin to hide the fact.

This is a replacement for a lost original.FOUR STARS because there is no way to track a lost Surface Pen if it falls into a location where you can't see it and you didn't see it fall. This is a design LACK on this device, because either they thought no one would ever lose one of these things (really?), or because they never considered it (not likely - these are smart people), because they didn't think it was worth the added expense to add this technology (most likely reason), or because they knew people would lose them and they saw it as an opportunity to sell replacements and make more money (this sounds cynical, but corporations have been known to use this type of reasoning). In any case, without a way to track a lost pen, I cannot give this five stars.NO LESS than four stars because the device works extremely well for its intended purpose, and because this particular item as I ordered it came with four additional replacement pen tips, in four different hardnesses. These replacement tips did not come with the original stylus I got when I bought my Surface Pro 4, so this is a nice extra, even though I haven't used any of them yet.The four replacement tips come in a nice holder, which has a clear plastic protector over the tips on the one end, and a tip-remover device on the other end.The replacement tips in their carrier are fairly small, and consequently easy-to-lose, so I have put them, along with the user manuals (printed in 2-point type, of course) into a zip-top bag, labelled with a Sharpie, to keep them all together and store them in my "computer extras" drawer.I looked at several off-brand replacement pens for the Surface, but decided to go with the original MS brand because of the eraser-end, which none of the others had, as far as I could tell.

I have a Surface Pro 3 and I got this Pen for 2 reasons. 1) I liked the features over the SP3 pen (Such as changeable tips and the eraser at the top) and 2) because I wanted to magnetically attach it to my surface.For the first part, this pen lived up to my expectations. The drawing feels much more natural with more friction on the screen. The eraser is great. manually selecting the stroke eraser in OneNOte was a PAIN given how many mistakes I make when writing (A lot).For the second part I ran into an issue. I wanted to mount the pen on the opposite side of the charging port because I wanted it mounted while using a Surface Pro 4 dock. Here's the deal. YES it does magnetically connect. But ONLY where the volume rocker is. The other magnet on the pen (located where the right click button is near the tip) does NOT magnetically attach to the surface. As such, gravity takes over and the pen tip drops to my desk.As a work around I bought these rather fantastic magnets:https://www.amazon.com/gp/product/B0033PHCU0/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1They are 0.375" in diameter which is just a mm or 2 larger than the side of the Surface Pro 3 and 1/32" in thickness which is just a HAIR thicker than the volume rocker. I placed it on the side where the right click magnet would attach to the surface and BAM, works flawlessly and stays perfectly intact. The only issue is the magnet SLIGHTLY interferes with the kickstand closing, but not enough to cause any issue or damage.Hope this helps someone!
