Very easy to use
I use these almost every day and would not want to be without them. I bought a second so that I have one available at each of my tanks.
While constructed well and easy to use, the 'mouth' on the tongs BARELY opens wide enough to get around even a frag plug. I thought it would be a wider grip then that. If you pick up a frag plug, you won't be able to put it down because the mouth is forced open just from picking it up.
