The problem still persists with electric drums which is the kick drum pedal essentially banging on the floor. The neighbours cant hear the drum sound but hear the vibrations travelling through the floor/walls.
A much cheaper alternative is to DIY a similar platform using some boards and a bunch of tennis balls cut in half[1]

It's not a substitute for a regular drum kit, but it you like hand drums it's pretty cool in combination with a DAW. There's a foot pedal you can use with it, but so far I'm I'm doing fine without it.
