Worth the money
It's worth the money if you know you play the DS a lot and for a really long time. $5.99 (US) is a steep price to pay for a mere DS accessory, but if you can afford to and you're thinking about buying it because your last session with whatever game left your hand cramped, then it's a really good idea to get this pen.

Only con is that the pen I got doesn't hold on to the stylus as tightly as when it first came in. Sometime during your gaming experience, you might have to take a break and push the stylus back up once in a while, but it's not a big deal. I'm on my 6th month and this $5.99 is definitely well-spent.

Innovative
For guys like me that have really big hands, this is a really great and innovative product. It's very comfortable to use and easy to attach to the DS. But mind you that this is not a whole new stylus, it's just a stylus holder. It comes with two retractable stylus that feels a bit flimsy by themselves but fits snugly into the holder once attached. It's much more ergonomic to use compared to the original stylus and now my fingers don't cramp as much after playing for some time. It's a product that I could easily recommend to anyone.

A lot more comfortable
The DS stylus by itself is not too bad, but this pen makes gameplay a lot more comfortable for the user. Especially for adult users with big hands like me.

The pin ships with 2 styli, which by themselves are perfect replacements for the DS stylus. While right out of the box the plastic pen shell does seem cheap and hollow, once the stylus is in place and the pen securely closed, it feels just as comfortable as any other pen.

I've had many hours of great gaming with this pen, which is why I find it so easy to recommend.

Great Pen!
My hand gets cramped from the tiny DS lite stylus so this was a perfect solution. Just slip one of the included stylus inside and closed it up. Feels great to hold, there's a padded rubber area to confort your fingers. It's short enough to fit into the Hori compact case too.

I love Hori products, they are always great!
Great Service from Play-Asia as well!

Nice to hold
It can be attached to DS.Simple,attach the pen in the DS hand strap hole.The pen itself is just a cover for original stylus.So,if your stylus turns bad,just change the stylus without changing the pen :)
