It seems to work just as well as the $80 oral-b
We originally started using an oral-b at the recommendation of our dental hygienist. Our last oral-b lasted 10 years, but eventually started turning itself on in the middle of the night.  We wanted another oral-b but didn't want to spend the $80 at Costco.  I wasn't sure why this was so much cheaper, but figured we wouldn't be out by much if it didn't work.<br />I can't speak for the longevity at this point but it seems to work just as well as the more expensive oral-b.  I'll update this if it breaks in the next year or so.<br />Update:  It's now been almost 2 years, with 3 of us that use it and just change out toothbrush heads.  That is now 6 person-years of use and still going strong
