I couldn't believe that it could do the job, but in the end, it is very good and practical! You tie it on the stroller - basket or wherever the baby sleeps and it creates a vibration as if you are moving the stroller on the sidewalk. It is completely silent. You will definitely need good rechargeable batteries (I use Eneloop and they perform very well), it takes 4 batteries and with moderate use (3-4 half-hour sessions during the day) they have run out. Attention, when placing it, the rocket should look at the sky, the more it leans, the more likely you are to press the button and it doesn't start, sometimes you may need to turn it on and give it a little movement with your hand (shake) to start. A suggestion to the company for the next model is to equip it with its own rechargeable battery and USB charging.

Perfect product. It is a lifesaver for us. We use it constantly, both in the stroller and in the crib, and it really does the job. It could have been more affordable though!!!

Awesome, I have placed it in the baby's crib and immediately he falls asleep. It rocks the crib perfectly, truly the best purchase I have made. It saved us from the rocking

The batteries don't last long. It doesn't have good grip, it needs to have a specific shape and thickness of the surface to hold properly without slipping after a while. It shakes very well but it's too expensive for what it does.

Amazing discovery!! However, a major drawback is that the batteries don't last. They didn't even last a week, so we constantly have to use new batteries

Going for coffee and not having to push the stroller back and forth and keeping the baby asleep, priceless!!

They gave it to me as a gift and I can say it was the best. It shakes the twins' stroller, very helpful. The babies sleep more easily. I would highly recommend it!

Personally, it didn't help me. The way it works, I also didn't like. I believe that there are much more user-friendly products on the market.

The baby was soothed by the vibration in the relax, so by placing it in his crib, we were saved during his nighttime sleep. It worked effectively for us and we recommend it!

The device is very useful. We have placed it in the crib and it saves us from rocking until the baby falls asleep. The low speed is sufficient - at high speed, it can wake the baby up instead of putting them to sleep. It also depends on where it is placed, as it may require a stronger vibration in a stroller. The batteries worried me at first, but since the device automatically shuts off after about half an hour, depending on usage, they can last for half a month or a month, so it's not ultimately a big problem.

Great discovery!! We have saved a lot of shaking at home.. Get it with closed eyes (along with a good set of rechargeable batteries..)

Excellent for soothing, pacifying, and sleep!!!! The only drawback is that as the child grows and gains weight, the swinging performance decreases.

As a system, it is very good. You can adjust it almost anywhere you want and the vibration it causes is quite good. Its main drawback is that it is not rechargeable. The batteries last only 3-4 hours depending on the intensity, so you constantly need batteries or rechargeable ones.
