Sulastic Springs

I researched these a few years ago for my older TV. Decided not to get them due to reading a significant number of negative reviews. I can overlook some minor complaints, but I can't overlook someone who says their shackle flipped over because of a rough road condition, causing the vehicle to become Immediately immobilized. If I recall correctly, there were multiple reviews along the same lines. Perhaps they've improved the product now...??
