These gloves do exactly what they are supposed to. They are very rugged and don't rip or get caught on my live rock etc. No leaks whatsoever. Another great thing is that at 6'1" they cover almost my entire arm and I can reach to move corals / rocks on the bottom of my 90g without an issue. I only wish they were a little more snug, the looseness reduces your hands sensitivity to movement, and sometimes this causes me to knock into things.
