Gllass Hole Saw Question

Got a question for those of you who have drilled your own tanks before. I know the glass-holes hole saws are supposed to be good ones. I was going to buy one, but I purchased an Eshopps Eclipse overflow box and it came with a 60mm glass hole saw. For those of you who have experience with drilling glass, does this saw look decent? For some reason it wasn't what I expected it to look like.

Should I use this one or just buy one from glass-holes?

Thanks in advance!
