    • Good product
Size: 4-6 Yrs
I like this adjustable costume. My child loves Dinos and he was able to enjoy this for 3 yrs. Transitioning from short looking stuby legs to looking like the perfect fit. Light weight needs good batteries to function properly. We walked around 1hr on Duracel and then gave candy for 1hr extra. FYI The cheap batteries were drain quicker, not lasting. I took batteries out every yr before putting away. ... show more

    • Kids loves it. perfect for Halloween
Size: 4-6 Yrs
I bought this for my 4 year old who loves dinosaurs. This costume has an adjustable drawstring around the waist to fit different sizes. The costume is made of high-quality material that is durable and comfortable. the fan does not come with batteries so make sure you have 4 AA batteries ready. The costume is easy to put on and take off, and it comes with a storage bag for convenient carrying. The costume looks realistic and cute. if your child loves riding a T-Rex and pretending to be a dinosaur trainer like my son, he or she will love this costume! This costume is a great gift for any dinosaur lover, and it will provide hours of entertainment and laughter. The quality for the price is beyond my expectations. ... show more

I got this inflatable dinosaur costume for my 4-year-old last Halloween, and he absolutely loved it! It was a huge hit then, and he still plays dress-up in it regularly. It fits him perfectly and inflates quickly with no issues. All his friends at daycare loved it!!! It’s held up surprisingly well for how much it’s been used, and it’s always a crowd favorite — whether it's trick-or-treating or just stomping around the house pretending to be a T-Rex. Highly recommend for any little dino-lover! ... show more

Cute costume for a kid!! I mean what kid hasn't dreamed of being a dino rider! The hat was way too small more for a baby but the blowup was great no issues at all! Make sure to use quality batteries

    • Great costume.
Size: 7-10 Yrs
Hilarious costume. The fan drains batteries fairly quickly, but keeps the costume blown up nicely. I wouldn’t recommend this costume for use in colder climates as it is fan operated. Fit my eight year old just right and he had no issue trick or treating in it for hours, so it had to be comfortable.
