I've had both the sure grip and a sedra impeller "burst". The sure grip I didn't even notice until I went to use it on my 180gal (previously used on my 90) and it fell apart as I was looking at it. Makes me wonder if thats why my tank was having some issues towards the end of my 90gal. I'm sure glad I didn't put it into my 180 blindly. On the flip side, my tunze magnets are doing well with no issues after many years (bought used).
