I recently picked up a clear rectangular Eshopps frag rack. I'm very disappointed. The holes do not fit any of the frag plugs that my frags are on, and the magnets won't hold the rack up once the frags were finally made to fit the holes. I had to use a magfloat to help support the rack. I wouldn't recommend this frag rack to anyone unless you have very thin glass. After hearing about Marlins new frag rack from Blackrockreef I ordered there large rack to replace my Eshopps. Hope this saves anyone thinking about purchasing one some money.
