Review (2/5): HAD TO RETURN:  I LOVED this and it did not hold up long term.
UPDATE: I have only had this a short time and will return it as the attachments will not lock into place and fall off during use. Since this gets hot it is a bit of a hazard to me. Attachment has gotten stuck in my hair when it fell off.
I may try ordering it again and see what happens.
Original Review: This is the right size to add curl to your hair where many of these are just so large it is not possible. Another product I bought was great but was simply too large to do anything but straighten hair. This has that attachment too but the round one is wonderful.
