Tramp has been great so far, beefy and looks great in the yard

We left a google review but figured should leave one here as well. We have had the K9 for about 6 months now and so far the trampoline has been great. Kids love it and seem to really like the black springs and the assembly was easy with very little hardware. The zippers made connecting the enclosure feel like a dream :-)

Best Bounce with PianoWire Springs

This tramp is super heavy duty and comes with Black PianoWire springs which gives the best bounce. Easy to assemble with very little hardware and the nice sleek black look.

Awesome Trampoline

Easy to assemble solo, high quality parts. The instructions could use a little more detail. For example I only realized there was a spring puller tool included after I was done. Otherwise, its a great Trampoline!

Love the Beast!!

We have owned several other trampolines and this has been by far the best!! Super solid and sturdy.. a Beast!! The design and quality of materials has obviously been very well thought out. I'm impressed with how well it handles multiple jumpers. Toddlers to parents, everyone loves it! A+ on the full experience; ordering, communications, delivery and set up.

This is our our first trampoline. After months of researching quality, cost and size, I came across Beast. I read the reviews on ALL the competitors to see what people said about pros and cons. I was sold on the K9 10x17.
It’s fun! It’s big. It’s not squeaky. It’s strong enough/tough enough to hold our very large family. It feels sturdy and safe, easy to assemble, well packaged, and customer service is A+.

Mary Vaughn
Best trampoline ever!

I put this together with the help of 2 - 11 y/o boys. It was super easy. Kids absolutely LOVE it!

Maria Magliocchetti
Best trampoline out there!

It’s amazing! My kids love this trampoline. It’s huge and really sturdy. We added the assembly through amazon and so happy we did.

Sarah Tarnanen
Worth every cent!

We have had the Beast K9 10x17 a little over a week. My kids were eagerly awaiting its arrival. Easy to assemble, my thirteen year old put it together with his friend. It’s built sturdy and the ladder is solid. It gets the kids outside and off their electronics, my husband too. Has phenomenal bounce, making it easier to master their tricks. Its enjoyed by the whole family, mom included!
