Is a waste of money. Doesn't come with the parts to make it work. Total scam

Just AWESOME!
This launcher is super fun. It is very well made with metal components and boy can you get those water bottle rockets launched high! I definitely recommend purchasing additional bottle launch caps from the company as you may lose a bottle or two but this thing is amazing. The hardest part is the workout pumping the pressure into the system. At around 100psi you might never see your rocket again but boy is it worth every penny!

Okay start to a good kit. Half price elsewhere.
It's pretty good, leaked despite having sealant on the threads. Just use the supplied thread tape on everything and it will be fine. The fin adaptor leaks no matter what. It's okay under 50 psi, but anything over loses pressure rapidly. Overall this is a good kit that can be adapted. Be aware that the fins are fragile... looks like by design with sharp edges and strategic hollow channels in the right places for stress risers. I added a 45 degree adaptor for the pressure gauge. It will foul against the Schrader valve and not turn if it goes in straight as designed (see pic). Be aware that is is available elsewhere (deluxe kit) for less than half the price that I paid. Needs to come with another bottle adaptor... lose one bottle and you are finished.

Solidly built!
Seems well built and sturdy. Lots of fun to launch! The only downside is the tight spacing between the screw-in fittings on the main body. It’s a bit difficult to get the inline water shutoff valve aligned so it doesn’t interfere with the pressure relief valve. My school bought 10 of these and several of them were pretty tricky to get aligned no matter how much Teflon tape we used to limit the screw-in travel. Otherwise, a nice product!

Plan for a long assembly...
This product is difficult to assemble and use and should only be purchased by adults with plumbing and fitting experience.

Blast off! Great for school use.
I use this for elementary nasa STEM activity. Coupled with an air compressor, we launched 90 rockets in 60 minutes without any failures. Only downside is you have to use their nozzles which are EXPENSIVE! Overall, a good launcher for school use.

The pump is not included
I’ve never flown it, but the pump does come included. $100 bucks I thought it would be included. Disappointed. I’ll have to buy a pump

I am completly blown away with the quality of this product. Certainly made to withstand thousands of launches. Looking forward to teaching the kids the physics behind water rockets. Thanks a million.

Great fun with the kids, make sure you use air compressor fittings. I have plans for better rockets, see how high we can go.
