Worth it!
I was nervous spending so much on a Halloween costume. We just opened it and so far so good! My son is 43” tall so by the size chart he’d be a small, but he’s 45lbs. I didn’t know if I should order a small or medium. My son is four and a half. I ordered the small and I’m glad I did. The medium would have been way too long. I had to look for instructions for the straps. But the quality is good and my son loves it!

My Son Loved Optimus
The only thing I had an issue with with this product was it could’ve been made better. I have an opinion that costumes for three and four-year-olds really should be manufactured a little higher quality. Unfortunately, my son ripped his a little bit which we were able to sew up, other than that the overall quality was OK, which is the only reason it still gets a five star review

Bulky but nice
It’s expensive and bulky. More of a pain for trick or treating to run in… but cute nonetheless,- and when your grandbaby wants to be Optimus Prime that transforms… you spend $120 + for a total of 2 hours.

Not worth the money
After spending this much money on a costume that my son would wear on his birthday, I was disappointed to see I received a pre opened/returned item. The bag which holds the costume was torn on the zipper and items were missing. The quality seems good which is why I’m giving 3 stars BUT FOR THIS AMOUNT OF MONEY I believe I’m owed a new costume and not a used or returned one.

Don't waste your money
This costume is a joke and for over $100 it should be made way better. It came with 2 right arm pieces, the arm and leg pieces don't stay up they slide off to where he can't even walk, the cab does not stay up right and folds in all the wrong places. For how much it cost I thought for sure it would be good quality. My grandson is super disappointed going return this junk. I am not sure how it got such high reviews I wish I could put 0.

Great costume!!
This is an awesome costume! I don’t understand the negative reviews! The quality is 100% worth the price! My 6 year old LOVES this costume and it is so darn cute! Would buy all over again! I wish there was more of the other characters so I could buy for his siblings!

Excelente articulo
Me encantó el artículo, la medida exacta, el traje viene tal cual como viene en la foto. Valió la pena la compra, todo es de excelente calidad, viene en su bolsa de tela para guardarlo perfectamente. Solo los guantes un poco pequeños, pero lo demás está perfecto.

Happy boy but not worth the price
Our son loved the costume but personally don’t believe it’s worth £90…

Good quality material
Very well made. Nice and warm for cold season and straps allow for a coat as well. By no means is this a cheaply made costume .

Missing left hand glove
Arrived with two right-hand gloves. Trying to get a left-hand glove, but the seller's contact details are incorrect and I can't get through. Cute costume, but huge. Far too large for my 4-year-old and almost fits my 10-year-old. (Ordered size 4-6). No instructions on how to fit the main box section straps to the child's body. It just floats around weirdly however I attach it. Bit of a mystery there.
