When clicking that link it came up with the last time I've purchased it. So as a random Internet stranger I can actually vouch for these.

I've got an old Sonicare travel toothbrush that used that as a charger and really didn't want to pack another cable. I've bought another pack because I ended up giving one away to a friend that lost the cable for a digital camera they use for work, and cannot use their cell phone for compliance reasons.

In both cases it has worked fine for just charging, and for data transfer.
