Does anyone know if using the product "Trailer Legs" cause/promote broken leaf springs?

I don't see any way they could cause a spring to break.
The Brand maybe new but the lifting devise for one or all axles for working on the suspension or storing the trailer for winter isn't new.
Several similar devices/brands have been around for years that lift the trailer from the axles next to the Ubolts. https://seasense.com/collections/trailering/products/easy-lift-jack
