My dad uses this fan A LOT and LOVES it.  I can see why: It kicks out a lot of air.  I borrowed it this summer on a very hot day and was amazed at how much power it had.  The only downside I found is that it is loud, but if you are looking for a handheld fan that gives you big air, this is it.  After using 2 of these, you should be aware that these fans are hit and miss.  The first one I purchased worked like a dream for a long period, the second one broke and didn't work properly.  If the fan works, then it's a good fan but if you get a lemon, not so much.
