This is a good inexpensive dishwasher. Bought to replace "another popular brand" dishwasher that failed after about 10 years which is probably the average life expectancy for dishwashers. 
Plusses - very inexpensive, Does a good job cleaning dishes, fits normal sized openings. Negatives - This does not have a small or low load setting, so you can't save on energy costs compared to similar models. Small utensils rack. You'll need to purchase a certain sized water inlet fitting if you have an older dishwasher (sorry, don't recall exact details but can be purchased local plumbing supply, etc. Somewhat noisy but tolerable. 
Installed it myself in about half a day due to having to purchase the inlet fitting. Owned it for about 4 months and no issues. Interesting way it alternates the water from top rack to bottom racks for maximum cleaning pressure.
Longevity? Hope to get 10 years out of it if lucky.
