I did not like the feel of the rubber tip

Surprising quality for the price. Works with my iPhone and Android tablets.  Comes with 4 replacement tips.  I have large hands but these styluses (stylii?) fit well.  The stylus is shorter than a regular #2 Pencil but almost as thick.  They feel heavier than they look but are definitely not heavy or cumbersome to use.  Initially, I did not like the feel of the rubber tip, it seems to have air behind it, but now that I am used to it the tip feels fine.  The "eraser" end has a metal protusion that has a small hole that you could tie a string through to use as a strap.  Very pleased with the purchase.

The rubber is hard I thoughts it would be soft. They made my hands hurt at first but I am adjusting so it's getting better.

I bought this for its ergonomic properties as the name suggests. It is quite comfortable for the wrist. However, after a few hours of use my thumb felt quite uncomfortable. In order to grip this thing you have to exert more pressure on your thumb than you do in the typical claw grip you use on a standard mouse. The muscles in my thumb started feeling a bit stiff, and produced a slightly dull pain after a while. I have had repetitive stress problems in my thumb in the past, which this exacerbated. I returned it as it was not suitable for me.

The build quality otherwise felt good and the mouse performed well, but I would not recommend this if you ever have discomfort in your thumb.

I noticed having uncomfortable feelings on finger tips more than usual, Then I tried the titanium nylon strings from D'Addario, Found much better on finger tips.(and sound too !)

Price seems appealing but the rubber on clips is very very slippery, it feels like someone put a lubricant allover the rubber.  I only needed it for one experiment so I can live with it, but it would be very annoying, and maybe useless for some, who want to really use it. I am planning to leave it in sun for a few days hoping it might rough up the rubber.

Not happy with, because it leaves marks on my screen as opposed to  the the rubber tipped pen I use.  its a lot bigger and easier to use.

I says it is double tip, and I specifically bought it because I wanted a finer point. The fine point tip is not rubber but rather hard plastic and it has no effect at all on my ipad. The rounded rubber side works ok, but no better than the free pen that I got at a conference which has a touch screen tip on it.

I love the pentel energel .7 tip, but the .5 needle tip does not glide as easily--the friction on the paper makes it harder to write and honestly it basically looks no thinner on paper than the .7. Disappointed and will definitely refill the barrel with .7 ink

I really wanted to love this pen, but I just didn't. It's great quality and has a cool design but it was a poor fit for me. I found the Fine nib to be scratchy and the pen feels unbalanced and weighty. It isn't that heavy of a pen, but to me it felt uncomfortable to write with.

Works OK -- in general these just don't give me what I'm looking for which is the same feeling as writing on paper.... The rubber tip is way better that most but still flaky if you try to write fast... Way over priced for what it does...

This stylus works for what i wanted it for, but it had a cheap feel. the tip is rubber and soft. If you wanna use it for writing on a tablet, good luck. As a simple pointer on the tablet its okay. The tip is big so it has no precision on where its at and sometimes you have to press harder. its not a natural feel. I wouldnt buy this again. I would go with one that has a hard rubber tip that is more defined so i can use it like a normal writing pen

I originally bought the smooth one of these and it is very uncomfortable to use as it slides between my fingers.
THis one is better because of the rubber on it, it doesn't slide while you are using it.
The tips are fragile, so if you buy this, be sure t buy extra tips (although they are pretty expensive) and close it when you are finshed with it.

This stylus has a very mushy rubbery tip.  It feels as though its a rather thin bubble, but I got it based on the reviews.  Once we received it, we tried using it on our iPad and it would not work at all.  The iPad does have a plastic shield the glass, so that may be why it won't work.  I tried it on my iPhone, which has a similar (but different) shield over the glass, and it did work OK.  It worked much better on a different iPhone that has a glass shield.  It may have something to do with the way it contacts the screen, not having enough conductivity with a plastic shield.  We are keeping these as back ups, but went ahead and ordered other stylus with microfiber tips.  The microfiber tips work great even on the iPad regardless of the shield.

It's not rubber - at least, it doesn't have a rubbery texture, but more like hard plastic.  This is important because I thought it would more or less stick to the metal my Jeep's cargo area - I don't have the seat or the carpet installed back there.  Instead, it's got a plastic feel, and it doesn't have any kind of heaviness to it at all, which made it slippery back there.  It wasn't quite big enough either in my opinion. I sent it back because $100 is a lot of money for something I'm not 100% satisfied with.

I am currently using the Galaxy Tab 10.1 and the shield protector ($29.99) from Best Buy.

This is a "rubberized" material and even your finger has a hard time on the screen. The rubber tip of this stylus does not mesh with the material of this particular screen protector. I would assume the other protectors similar to this would have the same problem.

I am returning this item and getting a cloth tipped stylus that has proven to work quite a bit better than the rubber tips of most of the cheaper stylus'.

Ultra touch tip not as good as on my previous pair (these are black tips, my previous was white). Harder to use on my iphone and ipod.

Works but just doesn't feel good. Rubberized back makes it hard to get my hand in without using both hands.
