Overall rating: 3.225 / 5 from 40 reviews.
The Cap Assembly is designed specifically for the BottleRocket Booster and Capsule bottles, intended for cold drinks. Opinions on quality and bottle durability vary, while feedback on the replacement lid is also mixed. Small parts present a choking hazard, so it is not suitable for children under 3 years of age.

"We have had to replace many of these but they usually last a year or two. However, one just broke after only a few weeks. Not happy."
"Love spout style, but wish it didn’t wear out. Glad to have a replacement available. These are the second and third replacement caps I’ve purchased for this (discontinued) style."
"My son broke two water bottle lids, so I ordered these. Fresh upgrade looked great and it was nice to buy just the piece I needed instead of the whole bottle again."
"Recien la voy a usar hoy. Pero cuando les enseñe a mis hijitos lo pudieron abrir."
"The very first one broke and we got a replacement of “whole water bottle” for free right away! I didn’t want to throw away the first one without lid so after maybe 2 years, I finally decided to get a lid. Ours is blue but I only have red and black as options. My son loves red lid with blue bottle. So original! My son is rough but the second one is going strong and hopefully the res replacement we got will last for a long time. My son calls it rocket bottle."
"We needed a replacement lid for our daughter’s thermos when hers broke at school. This arrived promptly and is in excellent condition. The lock mechanism is very secure, even a little difficult to open right now! We know this one will last many years."
"I have been only using planet box products for my child since 2017 however I keep having to replace things here and there. A few times planet box replaced parts for me but it becomes easier to just buy a replacement at times. Hoping these will last the school year."
"Thanks for your fast delivery 🤩"
"Great except often the unshaped metal piece that keeps the lid shut falls out."
"lasted for years"
