I have a family of 4 (2 adults, 2 kids), and I replaced all our brushes with Quip brushes. So far we're loving them! They're not too big for my mouth or my kids' mouths, and when it vibrates it's gentle and not harsh. This is especially nice when you have sensitive teeth. I think one of the things I'm looking forward to the most is the 3-month refills that are automatically sent (batteries and all). Everything I can automate is good!
I also like how solid the brushes feel. I got my husband and myself the upgrade brushes (gold and slate colored), so the handles are aluminum. The kids have the basic kids ones, and have plastic handles. So far they all have held up well. I've traveled with mine, and it held up well. Hopefully, replacing things is easy and fast. So far, so good!
Bottom Line: Yes, I would recommend this to a friend
