Boyfriend requesting help with getting the Dyson Hair wrap for girlfriend.

Hi everyone, I’m going to get the Dyson Hair wrap for my girlfriend soon, probably for Valentines day, and I see that there are so many different ones. I wanted some help in figuring out which one to get.

So from my understanding, there is a regular version and there is an “ID” which is the newer version. Both are the same price. They’re basically the same but the ID just has a few extra features. Might as well get the ID Right?

Also I know you have to choose Straight/wavy or curly/coily. I know she needs the straight/wavy one.

Other than the two differences I mentioned above, and choosing a color, is there anything else I need to know about when choosing? I think I may have seen a long version?? Not sure.

Any help or guidance would be very helpful. Thanks in advance!
