First a description of the Junior Stomp Rocket. Kit comes with a plastic rectangular "stomp pad" connected to a flexible tube. The end of the tube connects to one of the foam rockets (4 are includeded in the kit).  There is a small plastic stand that you can put together to use as a launch base.  Snap the plastic tube onto the base and stomp on the pad.  Air is shot through the tube and propels the foam rocket up into the air. The Junior Stomp Rocket advertises that rockets will soar as high as 100 feet.  The Product lists age range as 3-8 years.

The only real difference I found with the Ultra Stomp Rocket is that the foam rockets are a little larger.  Other than that, the equipment is exactly the same. The Ultra Stomp Rocket advertises that rockets will soar as high as 200 feet (maybe because they are bigger and shaped slightly differently).  The product lists age range as 8-12 years.

Both products list for a similar price.  Refill Rockets for both the Junior and Ultra models come in varying colors and sell (at least on Amazon) for under $10.

Whether you buy the Junior Stomp Rocket (listed here) or it's sister product&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Ultra-Stomp-Rocket/dp/B0006O8Q7Y/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Ultra Stomp Rocket</a>, you will be getting a fantastic toy!  This toy is so simple - no assembly required, no batteries, just easy to use and loads of fun!

I first purchased the Junior Stomp Rocket for my 4 year old for christmas. He LOVED it!  We had just had a snow storm, so we were delayed in taking the kit outside for a few days, but my son quickly modified the toy so that he holds the stomp pad under his arm and points the rocket and shoots the missiles around the house. Because the rockets are foam, they do not do any damage to walls, furniture, (or mom and dad, thankfully).  Once we were able to take it outside, my son literally played with this toy for hours adjusting the direction, and playing around with how hard you need to stomp to get the rocket to go really high. What a great toy!

I just purchased the Ultra Stomp Rocket for a birthday party my son attended. The gift was a big hit there too!  There was no difference in skill required between the Junior and Ultra models.

I would recommend either the Junior or Ultra Stomp Rockets. I see no reason why the Ultra version is rated such a higher age range. The only thing I found in favor of the junior version was the glow in the dark refill rockets.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Junior-Stomp-Rocket-Toy-Glow-in-the-Dark-Refills/dp/B000Y887XK/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Junior Stomp Rocket Toy Glow in the Dark Refills</a>.  For some reason, the glow in the dark refills only come in the "junior" size.
