My grandson has played with this countless hours.
My 5 year old son really wanted a lego police helicopter and I didn't want to pay a fortune to get one in a big City set. For $8 I really think it should be a little bigger and have a few more pieces (like 4 chopper blades instead of just 2), but he does love it and it comes with a minifigure which other bagged sets like this don't come with, so for LEGO PRICES, this isn't bad. I still think it should be closer to $5, but it is what it is.
All in all, this is a decent polybag. I think there are definitely better ones out there but if you can get it it's still not bad.
