I got this cartridge as a gift, and I like this cartridge a lot. It has some really neat cut outs for "celebrations." You can use it for any type of celebration-related LO. I've also used the cut outs for a lot of cards as well as many of my layouts. If you're going to get a cartridge with birthday related things, I would totally say to get this one. You'll get your money's worth on this one.
When I first bought this cartridge I thought it would be perfect for "kid" items. I have since found out that I use this on adult projects as well...boy, girl, man, woman, birtday, Christmas, and anything inbetween..This cartridge is a must have if you own a Cricut.
I bought this cartridge because I decided not to pay for commercially made birthday cards anymore. This is perfect for birthday cards, invitations, and any birthday or party scrapbook LOs.
I purchased this cart not knowing exactly how much use I would get out of it, but it has proven to be among my staple carts that I grab time and time again. It has a bunch of great birthday things which make cardmaking for all of those classmates' birthdays a snap. I use mine over and over again to creat neat and unique cards. I even made an entire birthday album as a gift with this cart! This is one cart to grab for your bug... you won't be disapointed!
I've used this cartridge a few times, but I wouldn't say that I've gotten my money's worth out of it yet. The designs are really cute. I've actually used it mostly for the numbers and the candy (on Halloween layouts!).
