Product with excellent value for money. Same price as the others but comes with a pretty sturdy storage case. I also liked that there is a 3/4" ratchet hole on the end as in most cases the spring is too close to the spring to put a box wrench on the end. That way, if things get tight, I can add a 6" extension and have enough room for a ratchet instead of twisting and then repositioning with each turn. As mentioned, the bottom hook is a bit flat and you may have trouble mounting the guard bar over a thicker spring. Other than that it hasn't given me any problems and as long as you use your common sense it shouldn't be a problem at all.
