Somewhat disappointing to purchase a chair rated for 400lbs and to have one of the wheels break in two less then three months later. Clearly the chair may be rated to support 400lbs but clearly the wheels are not. Thankfully I was able to swap out the wheels with my old chair, which I used for most of a decade without any broken wheels.

Otherwise the chair is comfortable, but I do miss the tilt functionality. 

Also, sometimes if you relax with all your weight back on the chair, the back seems like it wants to recline whether you want it to or not.
