As other reviewers have noted, this is a vinyl cap with plastic fake ears.  It's hot, so you can't wear it for too long.  The photo displayed by Amazon has been very well photoshopped if it is actually a model wearing this "wig".

I think if you know this ahead of time, it's worth the fairly cheap price.  I wore this to a Purim carnival and got a very positive response from people.  As long as you don't expect to look like you've just arrived from Vulcan, it's alright.

Live long and prosper.
