I'm using these straps to make a brace to keep my arms and shoulder back. I'll add a similar elastic section to give me a little stretch. The 3" widths means it doesn't cut into my upper arms. Products designed to do this reviewed here are too stretchy and expensive. And thanks for getting it here in a day. It's lowered my pain level already.

My daughters needed to replace the Velcro straps attaching their hoverboard to a kart T-frame and this item seemed to fit their needs, providing 12 straps per pack at a reasonable price. While they are not heavy duty, the straps seem strong enough to keep the T-frame in place under the usual conditions of use. My experience is that hoverkart plastic straps break not infrequently --no matter how thick they are-- more because of abrasion than other causes, so one solution is to provide some kind of a shield for these easily abradable straps.

Both published photos of broken straps and the inspection of the hoverboard with and without the kart frame attached indicate that the most vulnerable point of the straps is located immediately after the forward strap-retaining slot of the T-frame. It is here where the strap is likely to abrade on the ground when the corresponding driving lever of the kart is pushed forward too much in trying to make a tight turn. If a strap breaks, there is the risk of the T-frame coming loose and of the child falling down and getting hurt. To decrease the chance of this, I made two metal sleeves of 22-gauge sheet aluminum that fold around each strap's vulnerable point with the double aim of (a) protecting the straps, and (b) warning the child, by the noise of rubbing metal, that the lever has been pushed too far. This is shown in the figure, and works well so far.

The other vulnerable spot is at the strap-retaining slots themselves if the entire hoverkart is lifted in the air from the front of the T-frame --such as for transportation to the starting point-- as the straps then have to hold the entire weight of the hoverboard. While this would be more problematic with straps that are not heavy duty like these ones, the problem has no longer happened since the hoverkart is assembled (and later disassembled) at the point of use.

So far, they seem to work well.

The strength of the velcro is strong and holds together well

Good...no longer needed

The stabilizer blocks come in nice zipper bags. Got tired of packing and unpacking as the blocks don't come out in one group. Using these straps to bind them together. One quick tug and the bags are off. Very seldom need to remove any blocks from the stack so the whole stack goes right under the trailer.
