The balloons all looked great and my son loved all the sonic character balloons and large sonic and controller. The only thing that was a little disappointing was the star balloons would not float. They are littler than the other balloons and just wouldn't float like the other balloons. Overall, I would still recommend purchasing this set because they helped make my son's birthday Super Sonic!The balloons all held up nicely. The only flaw was that the rubber balloons smelt strong like gas almost. But the smell wore off though. I used a hand held manual pump and it was very easy to blow them up.Overall it's a good concept. If these were decorations for a toddler it would be ok. Im decorating for my 13 yr olds quaranteen birthday today and I am pretty disappointed. "Game on" balloon barely floats. The stars don't float at all. One of the sonic faces is faded on one of the balloons. Thankfully I have a recycled game controller balloon from a different company and will use this one as a table topper.I liked the different combination of balloons. The remote was awesome but it wouldnt float. The latex balloons were amazing no complaints. The round mylar balloons were ok. They started loosing air within a couple hours. The star balloons were slightly pointless. The main SONIC Balloon popped mid-inflation. I laughed and cried at the same time. My son was bummed. He is all about the party decorations. Amazon helped me out with the defective item. ThankfullyThe ballon were pretty cool great for my sons 7th birthday party inside. I will say that they did not float I ended up making the sonic, the controller and the stars a center piece on the table... other than that they did the job my son loved themIf you want to inflate them with helium, the Mylar balloons are too thick and heavy to float.The balloons were so small it was embarrassing. They were so small that i was not able to put helium in all of them because stores wouldn't do so due to the small size. The regular latex balloons were so cheap and thin that i was limited to how big they could blow them up. Due to the thinness of the lates balloons by the next day they werent holding up. The whole set of balloons compared to the 2 that i got from party city were ant size.The vinyl balloons are a perfect size! The sonic ballon is a bit bigger than the controller balloon but just right.
