Bought the 18" variety, as I like to cover the greatest area in the littlest amount of time.  It's well built and shares many of the qualities of a Great States and Scotts mowers.  The rollers are nice so you can see where you have mowed.  Height adjustment is a little cumbersome, but so are all the other models.  There is a good youtube video on height adjustment for the scotts.  It basically applies to all of these types of mowers.  Bought mine used.  Was missing a couple screws.  That is good since I go to the orange box store to replace all the screws with superior nylon lock nuts and hex bolts.  They will never some looks like the plastic wing nuts that come with these mowers.  I mow on a 1/3 acre property for the last 1.5 years with these reel mowers.  Great exercise, you don't smell like gas, and the mower is quiet.  Not much more you can ask for.
