Rated 1 out of 5�by TheWiseGuy Does not fit the Power Tank
While the Uniball Power Tank is a fantastic pen, this refill package is a sorry deal. For starters, it uses rather messy gel ink, instead of the simple and clean ink that the Power Tank comes with originally. And to install it you must disassemble the ink container assembly--no small feat--which I needed pliers to accomplish. Then you find out that these refills are 1/4cm longer than the original ink cartridge. So, since you can't fit it into the pen properly, you must either have the writing tip flopping out of the pen when retracted, due to having to remove a part, or jury-rig it into place, which makes extending the pen a sizeable effort. You are better off buying a new pen. These refills are worthless.

Rated 5 out of 5�by GIDGNAN BEST PEN EVER
I HAVE NEVER RAN A PEN OUT OF INK BEFORE. I WOULD CHANGE PENS EVERY OTHER DAY UNTIL I GOT THE POWER TANK. IT IS THE BEST INVESTMENT I EVER MADE, IT WRITES ALL THE TIME EXCEPT WHEN IT IS OUT OF INK. IT'S GREAT
