Absolute hit at the birthday party!
By DinoMom42 on March 2, 2026✓ Verified Purchase

Bought this for my son's dinosaur-themed 7th birthday party. I wore it as a surprise and the kids went WILD. Stayed inflated the entire 3-hour party. Easy to move around in once you get used to it. The viewing window is surprisingly clear. Only complaint: it gets warm inside after about 45 minutes, so take breaks if you're active. Would 100% buy again.

★★★★★
Won the costume contest!
By HalloweenKing on Feb 15, 2026✓ Verified Purchase

Hands down the best costume I've ever owned. Wore it to three different Halloween parties and won the costume contest at two of them. The battery fan is quiet enough that people don't notice it. Gets tons of laughs and photo requests. Great quality for the price.

★★★☆☆
Fun but runs small
By SkepticalShopper on Jan 28, 2026✓ Verified Purchase

I'm 6'1" and 240 lbs. The costume technically fits but it's tight around the midsection and the arms feel restrictive. If you're on the larger side, consider the Plus size. The fan works great though and the costume looks hilarious from the outside. Just wish they made it a bit roomier.

Customer Questions & Answers

Q: Can you sit down while wearing this costume?

A: Yes! The costume is flexible enough to sit in. It may deflate slightly but re-inflates immediately when you stand. Many customers report sitting comfortably at tables and in chairs.

Q: How long do the batteries last?

A: With standard AA batteries, expect 4-5 hours of continuous use. We recommend using rechargeable batteries for best value. The fan draws minimal power.

Q: Is this safe for kids under 14?

A: We recommend adult supervision for ages 10-13 due to the viewing window size. For kids under 10, check out our dedicated Kids T-Rex costume (PM-DINO-TREX-KIDS).
