This little pen is very convienent, faster and less effort than a pump. Plus, no filter to replace. Besides, it has a little strobe light, so the bacteria in your water gets treated to a disco just before it dies. The only cons are that the batteries are uncommon (CR123 lithium) and, when it gives off the light, it's hard to see unless you have a see-thru bottle. A small indicater LED on the top of the pen would be nice. But those are really minor details. In relatively clean water, this thing is head and shoulders above a pump.
