We had 4 of those, one each for my wife and 2 kids. The kids moved out several years ago, and I don't know if they're still using them, but my wife and I kept using ours until this month, when my wife replaced them with Philips Sonicare brushes. I did NOT throw the Oral-B brushes away, because they both still work fine, so I'm keeping them as backups, and if necessary, with new heads, they'll be as good as new!
