Never heard of them before your post - couldn't find a single video of them being played. They look like small aspires and this description from one store doesn't bode well:
"The LP601NY City Bongos are a great choice for beginners and schools. These affordable 6″ and 7″ wood bongos with rawhide heads sound and play great"
Found these Meinl acrylic bongos video online [about the same size] - don't look great either but at least you can hear them.

Kinda curious myself now about the 'Crazy El's"
Cheers
