"Our new PlanetBox BottleRocket is stellar! Absolutely leak-proof, insulated, and sturdy...it survived its first fall flawlessly.” -Venia L, Las Vegas NV

“My son’s drink in his BottleRocket was cold all day. I checked this before I washed the lunchboxes at 6pm and the water was still cold, where my other son's generic water bottle, even with an ice insert, was room temperature." -Chloe R, Austin TX

“We got a new BottleRocket and it's unbelievable! Leakproof, easy to clean, perfectly sized for little hands and backpacks, and no odd parts like so many other bottles we've tried before." -Kindra J, Portland OR

“First up is my family’s new favorite water bottle: the PlanetBox Bottle Rocket! Why is it our favorite? Because it keeps things cold. Coldy, cold, COLD! I like to fill it with water and ice cubes before we head out for a day’s adventure and I have come home many hours later with ice still knocking around inside the bottle. PlanetBox says it keeps things cold for up to 12 hours and it’s absolutely true.” - Wendolonia

“The BottleRocket Water Bottle is a really great water bottle too. My daughter will be using it all day long at her desk at school. I really like it because it is leak-proof, double-walled to keep drinks cold for up to 12 hours and it doesn’t sweat! No wet artwork comes home in my daughter’s bag! My daughter is also super excited to get a new set of magnets for her set. Since the lunchbox itself can last for years this way she can feel like something is special for the new school year. They also have customized magnets you can get made.” – Outnumbered 3 to 1
