Happin® Ultra Strong Trampoline Stakes Anchors High Wind, Ground Anchors Heavy Duty, Trampoline Tie Down Anchor Kit, Ground Stakes Galvanized Steel, Trampoline Accessories, U Shaped (8 Pack, Black)

They definitely work. We have had week long sustained 30 mph ground speed winds and these anchors held a 12 ft trampoline in place. Wouldn't have known the wind was so strong if not for a trampoline net. I mean it, these things gripped the ground and held on like it was it's job (it is it's job). Great value for what I paid, I was able to put 2 anchors at each leg of our trampoline (4 legs). They are so easy to install, push into ground and thenI would buy again except these hold so well that I won't have to buy new ones unless these corrode and break. If that happens ANYTIME soon, then the review would be updated.

Absolutely terrific product. Ordered again for other yard projects in my landscaping. Very sturdy and went it very deep so no way our trampoline will fly away unless a Tornado comes through. Hopefully Never. Highly recommend A+++++

Great use for tying down trampoline! Very sturdy product that's made out of good quality. Weve had several high winds and these held down the trampoline in place.

These are enormous and work great for our trampoline! We live in a very windy area and have never had an issue with our trampoline blowing away or even moving!

I used these on my greenhouse. Very strong and it keeps it anchored.

They lasted through many snow storms, rain storms and 65 miles per hour wind storms. Very Strom. Great product!

Okay, I rarely leave reviews. Tonight, our west Texas town was hit by a huge storm with tornado warnings and wind gusts over 100mph. I had the trampoline anchored down with four of these anchors. It did not even budge. These work great. I highly recommend!

Why did you pick this product vs others?:Great product! We often have high wind events and these have done the job of keeping our trampoline on the ground.
