My son is tall but skinny. The part that’s suppose to be the top of the truck does not stay on shoulders. It also collapsed fairly easily

My son loved it! Great costume for a affordable price! I suggest taking it out before use to get out all the stiffness so it will be more comfortable for them to wear.

Gear costume. Has different levels on how much your child wants to dress up. From just the mask and suit to adding the arm wheels or leg wheels to putting on the big box and being able to transform. The big box tends to be quite bulky to walk around with so it’s better to keep it off and offer it when they want to transform

My grandson loved the transformer custom, it was one of his Birthday gifts, and he was so excited, he said that it’s the best Birthday ever.
Kinda disappointed the parts are misshaped, the foam was squished during packaging so it doesn’t look like the picture on the package. The arm and leg elastic is too big for my 5 year old so I’ll have to safety pin them tighter to keep from falling down his arm and legs. I’m sure if I saw this in store, I wouldn’t purchase it but my son really loves Optimus Prime so we’re going to make adjustments to keep it on for Halloween.
my grandson loved it! this costume was just what he was looking for. We can't get him to take it off. great costume for the money.
I ordered 1 Bumblebee Converting costume and 1 Optimus Prime for my 3 year old twin boys. I ordered the Small as they are very tall and going by the recommended size chart. One of the gloves had a hole in it as we were trying it on the first time (not a huge deal). The converting car/truck part must be the exact same size for every single sized costume because it is HUGE and goes head to toe on my kids - in no way relative to the ordered costume size (and again - my boys are super tall - 99th percentile!). So - my boys are super uncomfortable in the bigger converting part while the full body costume fits fine and now they don't want to wear the truck or car part.... so a lot of money wasted.
The seller sent me a small tube of face paint instead. I thought the price was too good to be true. Now I have a dissapointed son.
Cool idea (probably stolen from the dad that went viral for building one for his son). However, not even remotely functional. Incredibly flimsy and when you transform into the car portion it pops the Velcro. Also, when you are a vehicle the whole car is flat and smooshed looking. Not even a little like a car. It was so disappointing and I’m not sure how anyone could give more than 2 stars. I bought 2 of these, one of each and they both are going back. Major fails.
Horrible. Very flimsy and droopy and doesn’t keep its shape. 100% do not recommend. Just find a suit that doesn’t transform.
