I have used Sequential Spelling for one year with my 2nd grader. I liked the way it is set up using the multi-sensory approach. It seems to have improved her spelling. I plan on using it with my older child as well this coming year. I like how it follows patterns to show them how to spell hard words that they wouldn't normally think they could spell - from "in", to "pin" to "inn" - and by day 10, "beginning"!
