Wasn't sure it would actually crawl like the videos, but it does. The movement looks real, the remote responds instantly. Hid it behind the tree and my kids lost it. Exceeded my expectations.

Thought it would look cheap in person. It doesn't. The crawl is smooth, the growl sounds spot on, and setup took less than a minute. Scared my husband three times in one day.

I've been burned by cheap decorations before, so I kept expectations low. This one actually delivers. Crawls like in the videos, remote works instantly, ready in seconds. Glad I gave it a shot.

Screamed for ten seconds, played with it all day
Set it up behind the tree before the kids came down on Christmas morning. My youngest was behind the sofa before I could say a word. Ten minutes later they were both crawling after it across the living room.
-
My wife made me turn it off
Had it crawling out from under the tree on Christmas morning. Two of the grandkids wouldn't come in for presents and my brother-in-law genuinely jumped. She said it was too much. It was perfect.

Three cars stopped in front of my house
I've put up the same lights on this house for eleven years. Never once had someone pull over. Put this out on the porch and by 8pm there were people filming from the street.
