Pros

Bump handle knocks D.E. and dirt off the flex tubes, so no backwash between cleanings
Uses far less water than backwashing a sand or grid D.E. filter
Air vents automatically to the pool

Cons

One-year parts-only warranty on the online (W3) version
Small filter area means draining and recharging D.E. more often than a large grid filter
1-1/2 in. ports limit flow with large pumps
