We have been saved from our fussy sleeper of a toddler by this NASA-derived technology. It's a bit of the future teleported into the present - a marvel of engineering and baby behavioral modification rolled into a tiny space-age package. It is absolutely genius and we're truly saddened these are apparently no longer being sold on Amazon (perhaps due to overwhelming demand or the global chip shortage or constraints in cross-ocean freight shipping). We strap this rocket to our stroller and the baby sleeps -- it's a miracle. Before buying this gizmo, I would wear out a pair of shoes every week while walking him to sleep. No more! At a press of a button, he falls into deep content slumber. Absolutely amazing this can be accomplished without implanting electrodes into baby brains.

I searched and searched to see if there was a product that was portable and versatile to create movement for our bassinet and also things like the car seat when not in motion, and found this. Very happy with the purchase! My only criticism is that the reusable "ziptie" is hard to undo, but after enough finagling it does come off to work on something else. Would recommend for anyone that needs movement for their babies and something that is easy to travel with!

this was helpful with my newborn, but the batteries die really fast. Im not sure i would buy again

UPDATE four years later: We ended up literally putting the rockit directly on my baby and it worked! She fell asleep! And that is the only way besides holding her that we were able to get her to fall asleep. Now using it for my newborn son (using it the way it was intended this time - attached to something) and it helps rock him to sleep even when nothing else does! So, despite the zip tie needing improvement, I've updated to five stars because this has saved our babies' sleep (and our arms and backs!). If rocking your baby is the only thing that will get them to sleep, try this!

Original review: One of the only places my baby will sleep is in a moving car. I was hoping using this with her carseat would mimic the movement of a car and calm her down. Unfortunately did not work for us. However the Rockit does what it is supposed to do - it provides a more rigorous vibration than a vibrating chair, and there are three different intensity settings. The design is very cute. However the zip-tie mechanism that secures the base to the stroller/carseat/etc is really hard to take off. You have to have another person hold the button while you push the tie up in order to pull it out. I tried getting in touch with customer service about this issue, because the first time this happened I really thought it was stuck, but their website does not offer customer service for USA. I also messaged them on Facebook but did not receive a response.

My daughter had colic for 4 months. And this is the only thing that helped her sleep. She could not stand being anywhere other than inside my arms. And it was hard to get anything done when I was holding her 247. So being able to put this on her little crib helped her sleep so much without me having to hold her. And the amount it shakes. It's amazing the performance on this thing. I would highly recommend buying rechargeable batteries though. Because it does go through batteries pretty fast.
